A Case of Adenoid Cystic Carcinoma on the Nipple with Axillary Lymph Node Metastasis / 대한피부과학회지

ABSTRACT

Adenoid cystic carcinoma of the breast is an uncommon type of breast cancer, and it accounts for 0.1% of all breast cancer. In contrast to the aggressive nature of extramammary adenoid cystic carcinoma, adenoid cystic carcinoma of the breast has a more favorable prognosis. A 55-year-old female patient presented with a 6-month history of a tender mass confined to the nipple of the left breast. A skin biopsy showed a linear and tubular pattern of atypical cells, which was consistent with adenoid cystic carcinoma. Left breast conserving surgery with axillary lymph node dissection was performed. The histopathology of the specimen showed a 1.5 cm sized mass localized to the nipple, and the axillary lymph nodes were positive for tumor metastasis.
