Merkel Cell Carcinoma: A Primer for the Radiologist

Abstract
OBJECTIVE. Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine tumor. The purpose of this review is to provide a comprehensive description of the staging, workup, treatment, and follow-up of MCC. CONCLUSION. Sentinel lymph node mapping and PET/CT are the cornerstones of staging of MCC. MCC is a radiosensitive tumor, and hence radiotherapy plays a major role in its management. Close follow-up with PET/CT helps in detecting recurrences of MCC.
