Carcinosarcoma of Breast - A Diagnostic Challenge

Abstract

Carcinosarcoma of the breast is a rare malignancy with two distinct cell lines described as a breast carcinoma of ductal type with a sarcomatous component. We present a rare case of a 34-year young female with a lump in left breast and contralateral axillary lymphadenopathy which on FNAC was reported to be a poorly differentiated malignant epithelial tumor with metastatic deposits in lymph node. On histopathology was diagnosed Carcinosarcoma and immunohistochemistry clinched the diagnosis.
