A case of carcinoma of the breast with metaplasia to chondrosarcoma: Light microscopic and immunohistochemical features

Abstract

The breast carcinomas with metaplasia are rare neoplasms showing both carcinomatous and sarcomatous elements. We described clinical behavior radiology findings and pathological features in case of breast carcinoma with heterologous chondrosarcomatoid metaplasia. The light microscopic features and the immunohistochemical markers of metaplastic carcinomas were highlighted in this paper with discussion focusing on histogenesis of this type of tumor.
