Abstract:
We encountered with a rare case of intraductal apocrine carcinoma of the breast. The patient was a 62-year-old woman who had undergone right mastectomy for invasive ductal carcinoma of the right breast two years previously. This time, she was diagnosed with the left breast cancer (Category4) because left mammography showed pleomorphic and segmental calcifications. Ultrasonography (US) revealed an irregular and low echoic mass. Histopathological examination by US-guided core needle biopsy showed apocrine carcinoma. Mastectomy with sentinel lymph node biopsy for breast cancer of the left breast was performed. Post operative histopathological examination revealed intraductal apocrine carcinoma without lymph node metastasis. Estrogen and progesterone receptors were negative, while androgen receptors were positive, HER2 score was 2+. Adjuvant therapy was not performed. She is under observation as an outpatient now.
