title: [Primary osteogenic sarcoma of the breast. Report of a case].
abstract: Primary osteogenic sarcoma (POS) of the breast is very rare. Only eleven cases have been previously reported in Japan. In this paper, we report an additional case of POS. A 30 year old female was admitted to our hospital with chief complaint of rapidly growing mass of the right breast. She was diagnosed carcinoma of the right breast and underwent a radical mastectomy (Br + Ax + Mj + Mn). Histological findings of the resected tissues revealed POS of the breast. After three months from the operation, local recurrence was demonstrated by an incisional biopsy. One more months later, chest X-P revealed bilateral lung metastases. Irradiation with 60Co for recurrence and chemotherapy using vincristine, methotrexate for distant metastases were not effective. However, cisplatin caused the necrosis of local recurrent tumor. She died nine months after operation. At autopsy, extended metastasis of tumor cells diffusely to the pleura, lungs, liver, adrenal glands, pancreas, peritoneum, fifth lumbar vertebra, skull, dura mater and left pulmonary hilar lymph nodes was observed.
