Metastatic Merkel Cell Carcinoma

Abstract

Merkel cell carcinoma is a rare, aggressive skin cancer that affects mainly the sun exposed areas in the elderly, especially the head and neck. Immunohistochemical analysis is necessary to establish diagnosis. We describe an elderly male who presented with hematochezia and was incidentally noted to have liver lesion on abdominal imaging, which was subsequently diagnosed as Merkel cell carcinoma.
