Introduction:
Metaplastic breast carcinoma (MBC) is a rare type of breast cancer. Osseous differentiation is a very rare subtype. Reporting this kind of case is important because its clinical course and line of management are poorly mentioned in the literatures. We present a very rare case of MBC with osseous differentiation. A 48-year-old female presented with painless hard mass of the left breast. Examination and investigations showed MBC with osseous differentiation. She was managed by operation with adjuvant chemotherapy.
Conclusion:
MBC with osseous differentiation is a very rare type of breast carcinoma presenting with hard mass and managed by mastectomy, axillary lymph node sampling and adjuvant chemotherapy.
