Noninvasive apocrine carcinoma is a rare disease, and is not defined by the ‘General Rules for Clinical and Pathological Recording of Breast Cancer’ adopted by Japanese Breast Cancer Society. A 72-year-old woman had a periodic checkup for breast cancer, and a lump was pointed out in her left breast. She was given fine-needle aspiration biopsy cytology, and the tumor was diagnosed as malignant, and she visited our hospital for an operation. The tumor was palpated as a hard, elastic, smooth-surfaced, and movable mass measuring 10mm in diameter in the upper (AC-region) of her left breast. Mammography did not reveal a tumor shadow. Ultrasonography showed in hypoechoic mass in the left breast. A wide excision and sentinel lymph node biopsy was performed. The histopathological diagnosis was a noninvasive apocrine carcinoma. There was no metastasis of the sentinel lymph node. Both estrogen receptor and progesterone receptor were negative. The HER2 score was 3. She had no recurrence as of 4.5 years after surgery.
