Merkel cell carcinoma (MCC) is a rare cutaneous neuroendocrine cancer that shows aggressive biological behaviour. Although it usually occurs on sun-exposed areas, it can sometimes be seen on non-sun-exposed sites. Here, we present the case of a 66-year-old woman with MCC arising from the right gluteal region that was treated with excision and adjuvant chemoradiotherapy. On follow-up after the 24 months, the patient 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.
