Merkel Cell Carcinoma of the Axilla and Adrenal Gland: A Case Report with Imaging and Pathologic Findings

الملخص EN

Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine carcinoma of the skin.

MCC is characterized by a high incidence of locoregional recurrence, and distant metastasis, and often requires short-term follow-up after treatment.

In this present paper, we describe a rare case of MCC, which presented as a palpable axillary mass and an incidental adrenal mass, and report on the ultrasonography, computed tomography, and 18F-fluorodeoxyglucose-positron emission tomography findings.

The patient underwent surgery and adjuvant radiation therapy.

Seven months after the initial diagnosis, distant metastasis was detected during a follow-up examination.
