Continuing Medical Education Sporotrichosis: an update on epidemiology, etiopathogenesis, laboratory and clinical therapeutics* Orofino-Costa, Rosane Macedo, Priscila Marques de Rodrigues, Anderson Messias Bernardes-Engemann, Andréa Reis Abstract in English: Abstract: In the late 90's there was a change in both the route of transmission and the people at risk for sporotrichosis. This zoonotic cat-man alternative transmission route elicited changes in strategies to control the epidemic. There was a progressive increase in the number of cases involving especially children and the elderly. In addition to becoming hyperendemic, uncommon clinical pictures like immunoreactive clinical presentations or severe systemic cases have emerged. New species were identified and classified through molecular tools using more virulent clinical isolates, like S. brasiliensis, compared to the environmental isolates. Likewise, different species of Sporothrix have been associated with different geographic regions. The serological and molecular techniques are used as an auxiliary tool for the diagnosis and/or for species identification, although the isolation and the identification of Sporothrix spp. in clinical specimen is still the gold standard. Currently sporotrichosis epidemics requires the knowledge of the epidemiological-molecular profile to control the disease and the specific treatment. Itraconazole, potassium iodide, terfinafine, and amphotericin B are the available drugs in Brazil to treat sporotrichosis. The drug of choice, its posology, and treatment duration vary according to the clinical presentation, the Sporothrix species, and host immune status. New treatment choices, including a vaccine, are being developed; nevertheless, more clinical trials are required to confirm its efficacy. |

Investigation Photodynamic action of the red laser on Propionibacterium acnes Ramos, Rogério Rodrigo Paiva, Jeferson Leandro de Gomes, José Paulo Franco dos Santos Boer, Nagib Pezati Godoy, José Maria Pereira de Batigalia, Fernando Abstract in English: Abstract: Background: Photodynamic therapy is a therapeutic modality that has consolidated its activity in the photooxidation of organic matter, which arises from the activity of reactive oxygen species. Objective: To evaluate the effect of red laser 660nm with the photosensitizer methylene blue on Propionibacterium acnes in vitro. Method: The experimental design was distributed into four groups (1 - control group without the application of light and without photosensitizer, 2 - application of light, 3 - methylene blue without light, and 4 - methylene blue with light). Tests were subjected to red laser irradiation 660nm by four cycles of 5 minutes at 3-minute intervals. Results: It was evidenced the prominence of the fourth cycle (20 minutes) groups 2, 3 and 4. Study limitations: Despite the favorable results, the laser irradiation time photosensitizer associated with methylene blue were not sufficient to to completely inhibit the proliferation of bacteria. Conclusion: Further studies in vitro are recommended to enable the clinical application of this photosensitizer in photodynamic therapy. |

Investigation Recurrent aphthous stomatitis in 18-year-old adolescents - Prevalence and associated factors: a population-based study* Souza, Paulo Ricardo Martins de Duquia, Rodrigo Pereira Breunig, Juliano de Avelar Almeida, Hiram Larangeira de Abstract in English: Abstract: Background: Recurrent aphthous stomatitis is a painful disorder of unknown etiology. It is among the most common oral mucosal lesions with high prevalence among young adults. Objectives: To conduct a population-based study with 18-year-old army recruiters to assess its prevalence and associated factors in male adolescents. Methods: Interview during clinical examination in the army. Results: In this group (2,427 interviewed adolescents) there was a RAS prevalence of 24.9%. Smoking, herpes labialis and socioeconomic status correlated with the outcome. Study Limitations: only male adolescents were interviewed. Conclusions: Our results showed high prevalence of RAS; association with higher economic level and herpes simplex was found. Protective effect of smoking was confirmed. |

Investigation Epidemiologic analysis of prevalence of the hyperhidrosis* Estevan, Fernanda Alvarenga Wolosker, Marina Borri Wolosker, Nelson Puech-Leão, Pedro Abstract in English: Abstract: Background: The present paper aims to study the prevalence of the various manifestations of hyperhidrosis in patients who sought treatment in a specialized ambulatory in the state of São Paulo. Objectives: Opposite to previous studies, this paper studies the different combinations of sweating sites, not being restricted to the main complaint site of the patients, but taking into consideration secondary complaints patients may present. Methods: This was a retrospective approach of a database containing more than 1200 patients in which were mapped: combination of sweating sites, age of onset, age spectrum, mean age, body mass index and gender of patients. Patients were categorized into four groups based on their main sweating site - palmar, plantar, axillary and facial. Results: We concluded that hyperhidrosis appears frequently in more than one site, being the main complaint that affects the most patients palmar hyperhidrosis, which appears early in the patients during adolescence. When there are two sites of sweating, the most frequent combination is palmar + plantar, and when there are three sites of sweating the most frequent combinations are palmar + plantar + axillary and axillary + palmar + plantar. Study limitations: This research has casuistics limited to a single care service for patients with hyperhidrosis. Conclusion: It is necessary to keep in mind that the disease manifests itself mainly in more than one location, with different intensities in each of the patients, generating a significant impairment of their quality of life. |

Investigation Evaluation of mean platelet volume in localized scleroderma* Bahali, Anil Gulsel Su, Ozlem Emiroglu, Nazan Cengiz, Fatma Pelin Kaya, Mehmet Onur Onsun, Nahide Abstract in English: Abstract: Background: Localized scleroderma is a chronic inflammatory skin disease characterized by sclerosis of the dermis and subcutaneous tissue. Platelets play an important role in inflammation. Following activation, platelets rapidly release numerous mediators and cytokines, which contribute to inflammation. Objectives: To evaluate whether there was any relation between localized scleroderma and platelet parameters. Methods: Forty-one patients with localized scleroderma were enrolled in the study. The control group consisted of 30 healthy subjects. Results: The mean platelet volume level in the patient group was 9.9 ± 1.3 fl and in the control group was 7.6 ± 1.1 fl. This difference was statistically significant (p< 0.001). The plateletcrit values are minimally higher in the patient group as compared to the control group. It was statistically significant (p<0.001). There was no significant difference in the platelet counts between the two groups (p= 0.560) In the patient group, there was no significant relation between the mean platelet volume levels and clinical signs of disease (p=0.09). However, plateletcrit values are higher in generalized than localized forms of disease (p=0.01). Study Limitations: The limited number of patients and the retrospective nature of the study were our limitations. Conclusions: This study suggests that platelets might play a role in the pathogenesis of scleroderma. Platelet parameters may be used as markers for evaluating disease severity and inflammatory processes. Thus, there is a need for more detailed and prospective studies. |

Investigation Skin disorders in renal transplant recipients: a retrospective study* Garrido, Pedro Miguel Clemente Borges-Costa, João Abstract in English: Abstract: Background: Immunosuppressive therapy, which is necessary to avoid graft rejection in renal transplant recipients, presents an increased risk of several pathologies, namely infectious and neoplastic. Objectives: To identify the most frequent skin diseases and their clinical and demographical risk factors within a population of renal transplant recipients. Methods: A retrospective study of renal transplant recipients referred to dermatology visit and observed for the first time from January 2008 to December 2014. Results: The study included 197 patients, 120 men (60,9%). Mean age was 50,7 years (±13,4). 12 patients (6,1%) had previous skin cancer. Infections were the most frequent reason of referral (93/197; 44%). From the total referred, 18,3% (36/197) presented pre-cancerous lesions. Malignancy was diagnosed in 36 patients (18,3%), with 29 non-melanoma skin cancers (14,7%) and 7 Kaposi sarcomas (3,6%). Ratio of basal cell carcinoma to squamous cell carcinoma was 1,1:1. Non-melanoma skin cancer was significantly associated with older age (p = 0,002), male gender (p = 0,028), history of previous skin cancer (p = 0,002) and higher duration of immunosuppressive therapy (p<0,001). Study limitations: Retrospective study, with data from the first visit in dermatology. We didn't made classification on skin-types. Conclusions: The great incidence of cutaneous infections and skin cancer is responsible for a significant morbidity. It is important to assure the regular dermatological follow-up of renal transplant recipients, which will promote the prevention, an early diagnosis and an efficient treatment. |

Investigation Final diagnosis of 86 cases included in differential diagnosis of American tegumentary leishmaniasis in a Brazilian sample: a retrospective cross-sectional study* Tirelli, Fernanda Vernal, Sebastian Roselino, Ana Maria Abstract in English: Abstract: Background: Cutaneous leishmaniasis is distributed worldwide, including Brazil. Its several clinical forms need to be distinguished from other dermatoses. Clinical similarities and lack of a gold standard diagnostic tool make leishmaniasis-like lesions a challenging diagnosis. Objectives. To report the final diagnosis of patients primarily suspected of having American tegumentary leishmaniasis (ATL). Methods. A retrospective cross-sectional study was conducted on the basis of medical records of 437 patients with clinical suspicion of ATL, registered in electronic hospital system between 1980 and 2013. Demographic, clinical, and laboratory data were compiled. Results. Analysis of 86 cases (19.7%) registered as ATL in one of the hypothesis revealed a different final diagnosis; 55 (63.9%) and 31 cases (36.1%) had skin and mucosal lesions, respectively. In 58 cases (67.4%), the requested PCR did not identify Leishmania sp. In 28 cases (32.5%), biopsies established the diagnosis and confirmed tumors, mycobacteriosis, and subcutaneous or systemic mycosis. Overall, 27% of the cases had inflammatory etiology, mainly nasal nonspecific inflammatory processes; 27% had infectious etiology, especially paracoccidioidomycosis and leprosy; 20% had neoplastic etiology, mainly basal and squamous cell carcinoma; 15% had miscellaneous etiology, including neuropathic ulcer, traumatic ulcers, idiopathic ulcer; 11% missed the follow-up. Study limitations: Some cases had no final diagnosis due to loss of follow-up. Conclusion. ATL can be confused with several differential diagnoses, especially inflammatory and infectious granulomatous diseases as well as non-melanoma skin cancers. Clinicians working in tropical areas should be aware of the main differential diagnosis of leishmaniasis-like lesions. |

Investigation Primary cutaneous T-cell lymphoma: experience from the Peruvian National Cancer Institute* Ruiz, Rosana Morante, Zaida Mantilla, Raul Mas, Luis Casanova, Luis Gomez, Henry L. Abstract in English: Abstract: Background: Primary cutaneous T-cell lymphomas constitute a heterogeneous and rare group of diseases with regional particularities in Latin America. Objective: To determine the clinicopathological features, relative frequency and survival among patients from a Peruvian institution. Methods: Primary cutaneous T-cell lymphomas were defined based on the absence of extracutaneous disease at diagnosis. Classification was performed following the 2008 World Health Organization Classification of Neoplasms of the Hematopoietic and Lymphoid tissues. Risk groups were established according to the 2005 World Health Organization-EORTC classification for cutaneous lymphomas. Data of patients admitted between January 2008 and December 2012 were analyzed. Results: 74 patients were included. Mean age was 49.5 years. In order of frequency, diagnoses were: mycosis fungoides (40.5%), peripheral T-cell lymphoma not otherwise specified (22.95%), adult T-cell lymphoma/leukemia (18.9%), CD30+ lymphoproliferative disorders (6.8%), hydroa vacciniforme-like lymphoma (5.4%), extranodal NK/T-cell lymphoma (4.1%) and Sézary syndrome (1.4%). Predominant clinical patterns were observed across different entities. Mycosis fungoides appeared mainly as plaques (93%). Peripheral T-cell lymphoma not otherwise specified and adult T-cell lymphoma/leukemia presentation was polymorphic. All patients with hydroa vacciniforme-like lymphoma presented with facial edema. All cases of extranodal NK/T-cell lymphoma appeared as ulcerated nodules/tumors. Disseminated cutaneous involvement was found in 71.6% cases. Forty-six percent of patients were alive at 5 years. Five-year overall survival was 76.4% and 19.2%, for indolent and high-risk lymphomas, respectively (p<0.05). High risk group (HR: 4.6 [2.08-10.18]) and increased DHL level (HR: 3.2 [1.57-6.46]) emerged as prognostic factors for survival. Study limitations: Small series. Conclusion: Primary cutaneous T-cell lymphomas other than mycosis fungoides or CD30+ lymphoproliferative disorders are aggressive entities with a poor prognosis. |

Investigation Outcomes of long term treatments of type I hereditary angioedema in a Turkish family* Akoglu, Gulsen Kesim, Belgin Yildiz, Gokhan Metin, Ahmet Abstract in English: Abstract: Background: Hereditary angioedema is a rare autosomal dominantly inherited immunodeficiency disorder characterized by potentially life-threatening angioedema attacks. Objective: We aimed to investigate the clinical and genetic features of a family with angioedema attacks. Methods: The medical history, clinical features and C1-INH gene mutation of a Turkish family were investigated and outcomes of long-term treatments were described. Results: Five members had experienced recurrent swellings on the face and extremities triggered by trauma. They were all misdiagnosed as familial Mediterranean fever (FMF) depending on frequent abdominal pain and were on colchicine therapy for a long time. They had low C4 and C1-INH protein concentrations and functions. A mutation (c.1247T>A) in C1-INH gene was detected. They were diagnosed as having hereditary angioedema with C1-INH deficiency (C1-INH hereditary angioedema) for the first time. Three of them benefited from danazol treatment without any significant adverse events and one received weekly C1 esterase replacement treatment instead of danazol since she had a medical history of thromboembolic stroke. Study limitations: Small sample size of participants. Conclusion: Patients with C1-INH hereditary angioedema may be misdiagnosed as having familial Mediterranean fever in regions where the disorder is endemic. Medical history, suspicion of hereditary angioedema and laboratory evaluations of patients and their family members lead the correct diagnoses of hereditary angioedema. Danazol and C1 replacement treatments provide significant reduction in hereditary angioedema attacks. |

Investigation Stevens-Johnson syndrome and toxic epidermal necrolysis: epidemiological and clinical outcomes analysis in public hospitals* Arantes, Luana Bernardes Reis, Carmélia Santiago Novaes, Alice Garbi Carvalho, Marta Rodrigues de Göttems, Leila Bernarda Donato Novaes, Maria Rita Carvalho Garbi Abstract in English: Abstract: Background: Adverse drug reactions are harmful and involuntary responses to drugs that occur at doses normally used for a given condition. Among them are Stevens-Johnson syndrome and toxic epidermal necrolysis, both rare and potentially fatal conditions. Objectives: To analyze the epidemiological and clinical characteristics related to patients diagnosed with Stevens-Johnson syndrome and toxic epidermal necrolysis in public hospitals in the Federal District - Brazil. Methods: Retrospective, cross-sectional and descriptive study, in which data were collected referring to patients hospitalized in the public healthcare system of the Federal District from 1999 to 2014. Results: Between 1999 and 2014, 86 cases of hospitalized patients with diagnosis of Stevens-Johnson syndrome and toxic epidermal necrolysis in the Federal District were reported. The majority of patients were women; the most affected age group was 0 to 10 years. Patients older than 60 years (elderly) represent 6.98% of the cases. Most patients admitted to the referral hospital were discharged. However, occurrence of deaths exceeded that of discharge in elderly patients. Limitations of the study: There is fragility in the registry of hospitalization of patients, both in the hospital information system and in the medical records of the reference hospital. Conclusion: There is a need for greater production and better dissemination of information on the incidence of adverse drug reactions. |

Review Moderate to severe psoriasis treatment challenges through the era of biological drugs* Vide, Júlia Magina, Sofia Abstract in English: Abstract: Biological therapy has revolutionized moderate to severe psoriasis treatment. However, despite being more effective than conventional systemic treatments, some patients do not respond or lose response to biotechnological treatments or develop drug-antibodies, interfering with its safety and efficacy. There are also clinical forms of the disease and patient profiles for which is pending further scientific evidence for more sustained therapeutic interventions. The continuous and more detailed knowledge of psoriasis pathophysiology has allowed identifying new therapeutic targets, which is expected to help overcome the challenges of individualized psoriasis treatment. |

Review Anogenital warts in pediatric population* Costa-Silva, Miguel Fernandes, Inês Rodrigues, Acácio Gonçalves Lisboa, Carmen Abstract in English: Abstract: The approach to children with anogenital warts in the context of sexual abuse is a challenge in clinical practice. This study aims to review the current knowledge of anogenital warts in children, the forms of transmission, and the association with sexual abuse and to propose a cross-sectional approach involving all medical specialties. A systematic review of the literature was conducted in Portuguese and English from January 2000 to June 2016 using the ISI Web of Knowledge and PubMed databases. Children aged 12 years or younger were included. The ethical and legal aspects were consulted in the Declaration and Convention on the Rights of Children and in the World Health Organization. Non-sexual and sexual transmission events of human papillomavirus in children have been well documented. The possibility of sexual transmission appears to be greater in children older than 4 years. In the case of anogenital warts in children younger than 4 years of age, the possibility of non-sexual transmission should be strongly considered in the absence of another sexually transmitted infection, clinical indicators, or history of sexual abuse. The importance of human papillomavirus genotyping in the evaluation of sexual abuse is controversial. A detailed medical history and physical examination of both the child and caregivers are critical during the course of the investigation. The likelihood of an association between human papillomavirus infection and sexual abuse increases directly with age. A multidisciplinary clinical approach improves the ability to identify sexual abuse in children with anogenital warts. |

Dermatopathology Is Ki-67, keratin 16, involucrin, and filaggrin immunostaining sufficient to diagnose inflammatory linear verrucous epidermal nevus? A report of eight cases and a comparison with psoriasis vulgaris* Peng, Jing Sun, Shu-Bin Yang, Pei-Pei Fan, Yi-Ming Abstract in English: Abstract: Inflammatory linear verrucous epidermal nevus and linear psoriasis are sometimes hard to differentiate clinically and pathologically. Although immunohistochemical expression of keratin 10 (K10), K16, Ki-67, and involucrin may be useful for differentiating both entities, these results have been reported in only a few cases. We collected data from 8 patients with inflammatory linear verrucous epidermal nevus, 11 with psoriasis vulgaris, and 8 healthy controls and evaluated immunohistochemical expression of Ki-67, K16, involucrin, and filaggrin among them. Ki-67 and K16 overexpression was similar in inflammatory linear verrucous epidermal nevus and psoriasis vulgaris compared with normal skin. Although staining for involucrin showed discontinuous expression in parakeratotic regions in 4 inflammatory linear verrucous epidermal nevus cases, it was continuous in the other 4 cases and in all psoriasis vulgaris cases. Filaggrin expression was present in hyperkeratotic regions but scarce in parakeratotic areas in both inflammatory linear verrucous epidermal nevus and psoriasis vulgaris. The immunostaining pattern of Ki-67, K16, involucrin, and filaggrin may be insufficient to discriminate inflammatory linear verrucous epidermal nevus from psoriasis vulgaris. |

Dermatopathology Pigmented Bowen's disease associated with high-risk HPV simulating melanoma of the hand* Lellis, Rute Facchini Veasey, John Verrinder Gonçalves, Renata Diniz Jacques Abstract in English: Abstract: Bowen's disease is an in situ squamous cell carcinoma of the skin with only 2% of pigmented cases reported. It is clinically characterized by papules and plaques of blackened surface that may be caused either by sun damage - usually in photoexposed areas in elderly individuals - or by human papillomavirus infection - usually in the anogenital region of young adults. Dermoscopic aspects of Bowen's disease are discussed for over a decade, but with no definitive criteria that would lead to a definitive diagnosis. We present a case of Bowen's disease affecting the finger of a 57-year-old Asian patient. The lesion clinically and dermoscopically simulated a melanoma. Histopathological findings suggested the diagnosis of pigmented Bowen's disease. Pigmented Bowen's disease should be considered a differential diagnosis of melanoma, since its clinical and dermoscopic criteria are unspecific. Histopathological examination remains the gold standard for the diagnosis of the disease. |

Special Algorithm for acne treatment: Ibero-Latin American consensus* Bagatin, Ediléia Florez-White, Mercedes Arias-Gomez, María Isabel Kaminsky, Ana Abstract in English: Abstract: Acne is a chronic, immune-mediated, inflammatory disease with high prevalence among adolescents. By compromising face, thorax and back, with the risk of permanent scars, it has a negative impact on the quality of life. Effective, safe and early treatment is the key to remission, while decreasing the risk of physical and/or emotional sequelae. The Iberian-Latin American Group of Acne Studies joined professionals with expertise and developed a practical therapeutic algorithm, adapted to the reality of Latin American countries, Spain and Portugal. This article intends to disseminate it with an updated review on a rational, safe and effective acne treatment. |

Case Report Granulomatous slack skin: a rare subtype of mycosis fungoides* Motta, Letícia Marra da Soares, Cleverson Teixeira Nakandakari, Sadamitsu Silva, Gardênia Viana da Nigro, Maria Helena Mazzi Freire Brandão, Leticia Stella Gardini Abstract in English: Abstract: We report a case of granulomatous slack skin, a rare and indolent subtype of mycosis fungoides. It affects mainly men between the third and fourth decades. It is characterized by hardened and erithematous plaques that mainly affect flexural areas and become pedunculated after some years. Histological examination shows a dense infiltrate of small atypical lymphocytes involving the dermis (and sometimes the subcutaneous tissue) associated with histiocytic and multinucleated giant cells containing lymphocytes and elastic fibers (lymphophagocytosis and elastophagocytosis, respectively). Patients affected by this entity can develop secondary lymphomas. There are several but little effective therapeutic modalities described. Despite the indolent behavior of granulomatous slack skin, its early recognition and continuous monitoring by a dermatologist becomes essential for its management and prevention of an unfavorable outcome. |

Case Report Ecthyma gangrenosum: a report of eight cases* Martínez-Longoria, César Adrián Rosales-Solis, Gloria María Ocampo-Garza, Jorge Guerrero-González, Guillermo Antonio Ocampo-Candiani, Jorge Abstract in English: Abstract: Ecthyma gangrenosum is a rare skin infection classically associated with Pseudomonas aeruginosa. We performed a retrospective study of all cases diagnosed with ecthyma gangrenosum from 2004-2010 in a university hospital in Mexico (8 cases, 5 female patients and 3 male patients, ages between 4 months and 2 years). The most common risk factor for ecthyma gangrenosum is neutropenia in immunocompromised patients. In previously healthy patients, immunological evaluation is important to rule out underlying immunodeficiency. Ecthyma gangrenosum in healthy patients has a high mortality rate and early diagnosis and aggressive antibiotic treatment is imperative as it can improve patients' prognosis. |

Case Report Primary cutaneous follicle center lymphoma* Costa, Eline Pinheiro Weba Lucena, Bethänia Dias de Amin, Gabriela Athayde Bittencourt, Maraya de Jesus Semblano Dias, Leonidas Braga Pires, Carla Andréa Avelar Abstract in English: Abstract: Cutaneous lymphomas are classified according to their cellular origin into T-cell lymphoma and B-cell lymphoma. The annual incidence rate is 0.3 per 100,000 population. We report a case of a 56-year-old male patient who presented with a two-month history of nodules of varying sizes, some ulcerated, on the face, abdomen, and upper limbs. Histopathological examination and immunohistochemical study confirmed the diagnosis of primary cutaneous centrofollicular lymphoma. Studies have shown an increased incidence of non-Hodgkin lymphomas in the last decade. We report an infrequent case that should be kept as a differential diagnosis of patients with nodules and cutaneous papules. |

Case Report Segmental lichen aureus: an uncommon presentation* Torraca, Pedro de Freitas Silva Murback, Nathalia Dias Negrão Wiziack, Nayara de Castro Freitas, Tânia Christina Marchesi de França, Greicy Mara Abstract in English: Abstract: Pigmented purpuric dermatoses are chronic vascular inflammatory conditions characterized by the presence of pigmented macules. Among its different presentations, lichen aureus is distinguished by the lichenoid conformation of its plaques and the predilection for lower limb involvement. Its segmented form is rare and difficult to control, especially in cases of symptomatic lesions. We report a rare case of segmental lichen aureus with six years of evolution associated with light itching. We also discuss the main therapeutic approaches to control the disease. |

Case Report Primary cutaneous amelanotic melanoma and gastrointestinal stromal tumor in synchronous evolution* Ortega, Fernanda Teixeira Kondo, Rogério Nabor Belinetti, Francine Milenkovich Okamura, Mariana Onuki Tuma, Bruna Abstract in English: Abstract: Gastrointestinal stromal tumor is rare digestive tract mesenchymal tumor, most often in the wall of the stomach. It is a benign neoplasm, but it can become malignant if not treated. We report a case of gastrointestinal stromal tumor that was discovered after abdominal ultrasonography during staging of a patient with primary cutaneous amelanotic melanoma. Mutation in the tyrosine kinase receptor could explain the development of two types of tumors in the same patient. |

Case Report Nevus lipomatosus cutaneous superficialis* Lima, Caren dos Santos Issa, Maria Claudia Almeida Souza, Mariana Boechat de Góes, Heliana Freitas de Oliveira Santos, Talita Batalha Pires dos Vilar, Enoi Aparecida Guedes Abstract in English: Abstract: Nevus lipomatosus cutaneous superficialis is a rare benign hamartomatous skin tumor characterized by dermal deposition of mature adipose tissue. Two clinical forms have been described (classical and solitary types). We describe a case of nevus lipomatosus cutaneous superficialis with a 13-year history of growth in a young woman who had a solitary skin-colored tumoral mass on the right buttock. Histopathological findings were typical and confirmed the diagnosis. In this case, the lesion was a skin-colored isolated mass, as described in the solitary type, but its localization and age of appearance were compatible with the classical type. The combination of simultaneous clinical findings of both types had not been published before. |

Case Report Dyshidrosiform pemphigoid localized on the hands in a child: a rare occurrence* Dayal, Surabhi Sahu, Priyadarshini Jain, Vijay Kumar Abstract in English: Abstract: Dyshidrosiform pemphigoid is an acquired autoimmune variant of bullous pemphigoid with persistent vesicobullous eruptions localized on the palms or soles, or both. It generally occurs in the elderly and is rarely reported in childhood. Hereby, we describe the first case of dyshidrosiform pemphigoid in a 12-year-old child, which was limited to the dorsal hands and treated successfully with dapsone (diaminodiphenyl sulfone). Along with this report, we also review the clinical features of various types of dyshidrosiform pemphigoid. |

Case Report Proteus syndrome* Rocha, Ritha de Cássia Capelato Estrella, Mariani Paulino Soriano Amaral, Danielle Mechereffe do Barbosa, Angela Marques Abreu, Marilda Aparecida Milanez Morgado de Abstract in English: Abstract: Proteus syndrome is a rare syndrome characterized by disproportionate overgrowth of limbs, multiple hamartomas, and vascular malformations. The cerebriform connective tissue nevi, also called cerebriform plantar hyperplasia, are present in most patients, and is the main characteristic of the syndrome. If present, even alone, they can be considered as a pathognomonic sign. This article reports a classic case of Proteus syndrome in a 2-year-old male patient who began to show a discrete asymmetry of the right hemibody in relation to the left one after birth, which increased over the months. He also showed cerebriform plantar hyperplasia and Port-wine stains, among other alterations. |

Case Report Syringocystadenoma papilliferum combined with a tubular apocrine adenoma* Léda, Luanna da Silva Brito Lins, Maria do Socorro Ventura Silva Leite, Everson José dos Santos Cardoso, Alberto Eduardo Cox Houly, Ricardo Luis Simões Abstract in English: Abstract: Syringocystadenoma papilliferum and tubular apocrine adenoma are rare benign sweat gland tumors. Syringocystadenoma papilliferum occurs alone or in association with other tumors. Although it is rare, the association of tubular apocrine adenoma with syringocystadenoma papilliferum developing in a sebaceous nevus on the scalp is well documented. However, the co-existence of these two tumors without the background of a sebaceous nevus has not been frequently reported. Syringocystadenoma papilliferum and tubular apocrine adenoma may have a histopathological overlap, but a few cases of a syringocystadenoma papilliferum combined with a tubular apocrine adenoma have been reported. Herein we describe an unusual case of syringocystadenoma papilliferum co-existing with a tubular apocrine adenoma located on the back of a 14-year-old patient in the absence of a pre-existing sebaceous nevus. |

Images in Dermatology Yellow dots in trichoscopy: relevance, clinical significance and peculiarities* Lima, Caren dos Santos Lemes, Luciana Rodino Melo, Daniel Fernandes Abstract in English: Abstract: Yellow dots are follicular ostium filled with keratin and/or sebum. Initially, they were exclusively associated with alopecia areata. Currently they have also been described in androgenetic alopecia, chronic cutaneous (discoid) lupus erythematosus, and dissecting cellulitis. Due to the growing importance of trichoscopy and its findings in the evaluation of the scalp, this article describes the main diseases in which yellow dots are a common trichoscopic finding, highlighting its characteristics in each dermatosis. |

Syndrome in question Do you know this syndrome? Ascher´s syndrome: clinical findings of little known triad* Donato, Carolina Mendonça Gama Melo, Daniel Fernandes Santos, Juliana de Noronha Abstract in English: Abstract: Ascher's syndrome consists of double lip, blepharochalasis and sometimes non-toxic thyroid enlargement. It is a rare, benign, rarely reported, and sometimes misdiagnosed condition that most often affects patients under 20 years old. The etiology remains unknown, although factors such as trauma, hormonal dysfunction and heredity have been suggested. Treatment based on surgical intervention is indicated to improve aesthetics or function. The presented case shows a patient diagnosed with Ascher's syndrome based on clinical findings such as double lip and blepharochalasis. |

What is your diagnosis? Case for diagnosis. Systemic light chain amyloidosis with cutaneous involvement* Gontijo, João Renato Vianna Pinto, Jackson Machado Paula, Maysa Carla de Abstract in English: Abstract: Systemic light chain amiloydosis is a rare disease. Due to its typical cutaneous lesions, dermatologists play an essential role in its diagnosis. Clinical manifestations vary according to the affected organ and are often unspecific. Definitive diagnosis is achieved through biopsy. We report a patient with palpebral amyloidosis, typical bilateral ecchymoses and cardiac involvement, without plasma cell dyscrasia or lymphomas. The patient died shortly after the diagnosis. |

Communication Nickel exposure from keys: a Brazilian issue* Suzuki, Nathalie Mie Duarte, Ida Alzira Gomes Hafner, Mariana de Figueiredo Silva Lazzarini, Rosana Abstract in English: Abstract: Keys are a significant source of exposure to metal allergens and can be a relevant problem for nickel-allergic individuals. This study aimed to perform nickel and cobalt spot testing among the 5 most common Brazilian brands of keys. Among the tested keys, 100% showed positive result to nickel spot test, 83,3% presented strong positive reaction. 50% exhibited cobalt release as well. Nickel release from keys is very common in our country and may cause a negative impact on sensitized individual's quality of life. Study's results highlight the importance of establishing directives to regulate nickel release in Brazil. |

Communication The pH of the main Brazilian commercial moisturizers and liquid soaps: considerations on the repair of the skin barrier* Gonçalves, Giovana M Brianezi, Gabrielli Miot, Hélio Amante Abstract in English: Abstract: The pH of the skin is slightly acidic (4.6 to 5.8) which is important for appropriate antibacterial, antifungal, constitution of barrier function, as well as structuring and maturation of the stratum corneum. This study aimed to evaluate the pH of the main commercial moisturizers and liquid soaps in Brazil. Thus, pH of the products was quantified by pH meter in three measurements. A total of 38 moisturizers and six commercial liquid soaps were evaluated. Mean pH of 63% and 50% of the moisturizing and liquid soaps presented results above 5.5, disfavoring repair, function, and synthesis of dermal barrier. |
