title: Metaplastic breast carcinoma with extensive osseous differentiation: a case report.
abstract: We present a case of a 77-year-old female who had a metaplastic breast carcinoma with extensive osseous differentiation. Her mammogram showed a largely calcified mass, but the pathology revealed that the calcification was ossification. The radiologic differentiation between an osteoid matrix and a dense calcification is discussed. Radiologic and pathologic correlation is also provided.
