Metaplastic carcinoma of breast (MCB) is a rare breast malignancy. It is important to differentiate metaplastic carcinoma from malignant phyllodes and primary breast sarcomas because of their differing biological behavior and prognosis. MCB is a rare heterogeneous tumor having areas of spindle, squamous, chondroid, or osseous elements in addition to the features of usual breast adenocarcinoma. Due to its heterogeneous nature, precise histological categorization has always been difficult, and these lesions have been given various confusing names.
