抄録

We experienced a case of unilateral multiple breast cancer in which two primary tumors arising in the right breast had each lymph node metastasis in accordance with each histologic type of the tumors.<br> An 85-year-old woman was seen at the hospital because of a right breast tumor. There were two palpable tumors comprising of a tumor 4cm in diameter in the EBD area and another tumor 2cm in diameter in the C area of the right breast. Ultrasonography of the right breast visualized the both lesions as hypoechoic and internally heterogenous tumor. The tumor in the C area was poorly demarcated. On mammography spicula were noted in the C area tumor. With needle aspiration cytology a diagnosis of adenocarcinoma was made. A modified radical mastectomy was carried out on December 18, 1995. Histopathologically the tumor in the EBD area was solid ductal carcinoma and another tumor was scirrhous cancer. Lymph node metastases were confirmed in area 1a and 1b; the lymph node metastasis in the 1a area revealed histologic feature of solid ductal carcinoma and that of 1b area histologic feature of scirrhous cancer.
