Metachronous Merkel Cell Carcinoma: A Case Report

Abstract

Merkel cell carcinoma (MCC) typically presents as an isolated cutaneous lesion with a measurable risk of regional lymph node involvement. Uncommonly, synchronous or metachronous lesions have been described to be attributed to a field effect. This case report describes a patient presenting with metachronous lesions, separated by several years, which cannot be attributed to a field effect given the tumor distribution.
