Microcystic Adnexal Carcinoma Treated by Mohs' Micrographic Surgery / 대한피부과학회지

ABSTRACT

Microcystic adnexal carcinoma (MAC) is an uncommon skin appendage neoplasm with both follicular and sweat duct differentiation. It usually extends microscopically far beyond assessed clinical margins and spreads locally in the dermal, subcutaneous fat, muscle, and perineural tissue planes. Although its metastasis is very rare, local recurrence rate after standard excision is 40~59%. Recently, Mohs micrographic surgery (MMS) was introduced for the treatment of MAC and a more favorable cure rate has been reported. We report a case of MAC, which was treated by MMS, which concurred with thymoma and thyroid papillary carcinoma in a 50-year-old woman.
