The Great Mime: Three Cases of Melanoma with Carcinoid-Like and Paraganglioma-Like Pattern with Emphasis on Differential Diagnosis

Abstract

Melanoma is among the most aggressive tumors, with different histological patterns of presentation ranging from the usual and easily diagnosable pictures to complex patterns of difficult diagnostic interpretation. Here, we present three cases of a very rare melanoma variant described as “carcinoid-like” and “paraganglioma-like” in the literature, and a brief review of the current literature of the very few cases described to date.
