Abstract
A rare case of invasive ductal carcinoma within a fibroadenoma of the breast in a 42-year-old woman is reported. The patient had a well-defined mass, measuring 6.0 × 5.0 cm, in the upper lateral quadrant of the left breast. Physical examination suggested fibroadenoma. Ultraso-nography and mammography revealed some malignant findings. Needle biopsy demonstrated fibroadenoma. Frozen section revealed invasive ductal carcinoma, scirrhous type, arising in a fibroadenoma; muscle-preserving mastectomy was performed. Only 16 cases of carcinoma within a fibroadenoma of the breast have been reported in the literature in Japan. Carcinoma in a fibroadenoma should be treated on the basis of the therapeutic criteria for ordinary carcinoma.
