Fine needle aspiration cytology of accessory axillary breasts and their lesions.

Fine needle aspiration cytology (FNAC) of 25 cases of accessory axillary breast tissue was performed during a five-year period. The patients were referred to the cytology clinic with clinical diagnoses of axillary lymphadenopathy (16), accessory breasts (5) and lipomas (4). FNAC revealed accessory breasts in 17 cases, fibroadenoma in 7 and fibrocystic disease in 1. Of the 17 accessory breasts, 12 were clinically thought to be lymphadenopathy or lipomas. FNAC remains an important tool in preventing unnecessary surgery in such cases.
