Endocrine mucin-producing sweat gland carcinoma of the cheek

Abstract

Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a low-grade adnexal malignant neoplasm. We report a 90-year-old man who had a hard, dome-shaped tumor approximately 9 mm in diameter on the left cheek. Dermoscopy showed an overall, non-uniformly light-pink tumor with crust. The diagnosis of EMPSGC is made histologically from excisional biopsy. No signs of recurrent disease were evident at 42 months postoperatively.
