Hidradenitis suppurativa (HS) is a common skin disease in children and young adults. In this report, we describe an unusual case of HS presenting as a mammillary fistula (MF) in a teenage female. A thorough dermatologic history and exam resulted in diagnosis of HS. Identifying the underlying disease is key to appropriate treatment of a relapsing MF in the setting of HS.
