Apocrine carcinoma of the breast is a relatively rare subgroup of breast tumors and comprises 1-4% of all breast carcinomas. The case is a 49 year-old postmenopausal woman. Two different lumps located near to each other at the left upper quadrant were both reported as invasive ductal carcinoma after core needle biopsy. The patient had undergone breast conserving surgery and sentinel lymph node biopsy of axilla with blue dye after wire localization of the masses. Since the lymph node biopsy was found to be metastatic, level I-II axillary dissection was performed on the patient. Pathology revealed apocrine carcinoma with 1 of 16 dissected lymph nodes and was evaluated as metastasis and the oncology department planned chemotherapy with 4 cycles Epirubicin-Cyclophosphamide protocol followed by radiotherapy.
