Primary chondrosarcoma of the breast.

ABSTRACT

Mammary sarcomas are uncommon tumours. Of these, pure chondrosarcoma without any other area of epithelial or mesenchymal differentiation feature is even rarer. This excludes tumours like malignant cystosarcoma phylloides and metaplastic carcinoma where malignant cartilaginous areas may be present. Further, primary chondrosarcoma arises from breast stroma and not from underlying bone or cartilage. Here is this case, a 46-year-old female was presented with a huge lump in her left breast. FNAC reported it to be a case of infiltrating duct carcinoma. Microscopically a well differentiated chondrosarcoma was identified. The case is presented because of its rarity.
