Merkel cell carcinoma in a male breast: a case report

Merkel cell carcinoma is a rare skin neoplasm and has not been reported yet in a male breast. We present a case of 74-year-old patient who was referred to the breast clinic with a lump in his right breast, which led first to the core biopsy followed by radical mastectomy and axillary clearance. The clinical characteristics, gross, microscopic and immunohistochemical findings and management of this lesion are discussed. Surgical excision remains the main option for treating this lesion including prophylactic lymphadenectomy and local radiotherapy.
