Microcystic Adnexal Carcinoma in the Mental Region

Microcystic adnexal carcinoma is a rare tumour, first described in 1982. Prior to the recognition of microcystic adnexal carcinoma, instances of unusual basal cell carcinoma, sweat gland carcinoma, and trichofolliculoma had been reported. Microcystic adnexal carcinomas are slow growing and demonstrate aggressive local behaviour and a high recurrence rate. The mainstay of treatment is surgical excision using frozen sections to check the peripheral and deep margins. This report is of a microcystic adnexal carcinoma in the mental region of a 69-year-old woman.
