Merkel cell carcinoma of the gluteal region: a rare case report and literature review

Abstract

Merkel cell carcinoma (MCC) is a rare cutaneous neuroendocrine cancer that shows aggressive biologic behavior.

In the 24th month follow-up, the case was disease and recurrence free, representing the longest survival among patients with gluteal MCC. Early diagnosis and treatment are important to improve survival rates in patients with non-sun-exposed MCC. Keywords: Merkel cell carcinoma, non-sun-exposed, Continuous...
