Malignant mesenchymal tumor of male breast: primary chondrosarcoma.

Breast Sarcomas have relatively been rare and accounted for 1% of all primary malignant tumors of the breast. Pure and primary chondrosarcoma of the male breast would be an extremely rare tumor. It might arise either from the breast stroma itself, or from underlying bone or cartilage. A 65-year-old man has presented with a rapidly growing breast mass since 5 months. Physical examination has established a large firm to hard mass with regular margins in the region of right breast. There was no axillary lymphadenopathy. Contrast enhanced MRI of breasts has shown a mixed-signal intensity multi lobulated cystic-solid mass (10.4 cm × 10.3 cm ×9.9 cm) appearing predominantly hyper intense on T2W and hypo intense on T1W. The tumor has diagnosed as a low-grade chondrosarcoma of the breast by histopathological and immunohistochemistry analysis. Right sided radical mastectomy with grafting has done. It has seemed to be very important to identify the mammary primary sarcomas as entity separated from the carcinomas of the breast.
