Cutaneous metastasis from gastrointestinal adenocarcinoma of unknown primary origin^*

Cutaneous metastasis is a rare manifestation of visceral malignancies that indicates primarily advanced disease. Due to its low incidence and similarity to other cutaneous lesions, it is not uncommon to have a delayed diagnosis and a shortened prognosis. We describe the case of a patient who presented with a cutaneous nodule in the sternal region as a first sign of malignancy.
