title: [Unusual sarcomas of the breast. Report of 3 cases].
abstract: Non phylloides sarcomas of the breast are infrequent malignant tumors that can be identified only at histologic examination since clinical presentation may not differ from the more frequent phylloides type. In addition to fibrosarcoma, leiomyosarcoma, rhabdomyosarcoma, angiosarcoma and liposarcoma, the stromal sarcoma of the breast has been recently identified. We report 3 such cases with heterologous components of osteosarcoma, chondrosarcoma and liposarcoma. A third case with an anti-sarcoma appearing post radiotherapy for breast carcinoma is also reported.
