title: Microcystic adnexal carcinoma in the axilla of an 18-year-old woman.
abstract: Microcystic adnexal carcinoma (MAC) is an uncommon adnexal neoplasm with a predilection for the head and neck. The tumor rarely metastasizes but is locally aggressive and commonly demonstrates perineural invasion. MAC occurs most often in older adults. This report describes a young woman with a MAC in her left axilla who required two stages of Mohs micrographic surgery followed by a wide local excision because of persistent perineural invasion in close proximity to the brachial plexus. Other cases presenting in the pediatric age group are discussed.
