title: Adenomyoepithelioma of the breast coexisting with ductal carcinoma in situ: a case report and review of the literature.
abstract: We herein report a case of adenomyoepithelioma (AME) of the breast with ductal carcinoma in situ (DCIS) involving a 71-year-old Japanese woman. She presented with bloody discharge from the left nipple. Mammography and ultrasonography showed a well-defined polygonal tumor. Fine-needle aspiration cytology of the mass and stamp cytology of the bloody nipple discharge showed malignancy. Mastectomy and a sentinel lymph node biopsy were performed. The final diagnosis was AME of the breast with DCIS. There are no reports of AME of the breast presenting with bloody nipple discharge; upon a diagnosis of AME of the breast with bloody nipple discharge, the possibility of the coexistence of breast cancer should thus be considered when encountering such cases.
