Abstract:
Microcystic adnexal carcinoma, also known as sclerosing sweat duct carcinoma, is an uncommon skin appendage neoplasm with both follicular and sweat duct differentiation. It typically occurs on the upper lip or central face of middle-aged patients but rarely affects the scalp. We report a case of microcystic adnexal carcinoma which developed on the scalp. A 65-year-old woman presented with a 10-year history of an asymptomatic, 1x1.5cm sized, firm, fixed, and dome-shaped mass on the scalp. A biopsy specimen showed a dermal tumor extending into the subcutis. Both the follicular and ductal structure, and CEA staining revealed a weakly positive reaction in the glandular structure of the tumor.
