Abstract :
Metaplastic breast carcinoma is a rare breast neoplasm, and metaplastic carcinoma with osseous differentiation is even rarer. It originates from a change in the differentiation of epithelial metaplastic breast tissue cells to squamous cell, spindle cell and/or mesenchymal appearance. We present a case of 49 year old woman who was diagnosed with metaplastic carcinoma of breast with osseous differentiation. This case is reported for its rarity.
