Merkel cell carcinoma with adrenal metastasis: a clinical case

Abstract

Merkel cell carcinoma is a rare primary malignant skin tumor with epithelial and neuroendocrine differentiation, which is usually characterized by an aggressive course with frequent local recurrence and a high metastatic potential. This article presents a clinical case of diagnosing Merkel cell carcinoma with secondary lesions of the adrenal glands, which is a rare localization of distant metastasis of this tumor with a low survival prognosis. Merkel cell carcinoma is difficult to diagnose due to its rare occurrence and can be mistaken for another dermatological disease. The patient's medical history was analyzed, starting from the outpatient stage of medical care until hospitalization for diagnostic surgery. The article is valuable for doctors of any specialty due to the difficulties in differential diagnosis of adrenal incidentalomas.
