Primary Neuroendocrine Carcinoma of the Skin in an Elderly Black Man: A Case Report

Abstract

Merkel cell carcinoma (also called primary neuroendocrine carcinoma of the skin) is a rare and aggressive skin cancer. Because of its variable clinical appearance, its diagnosis is often delayed. Here we present an atypical case of this tumor in an elderly Black man who experienced diagnostic delay, and eventually, fatal metastases. Primary neuroendocrine carcinoma is difficult to treat and often requires a multi-disciplinary approach. This case report highlights the importance of early diagnosis, and this tumor’s appearance in skin of color individuals, who are affected relatively infrequently.
