Carcinoarcoma of breast is rare tumor with aggressive behaviour and poor prognosis. Histologically it is biphasic tumor with epithelial and mesenchymal component. Very few cases of carcinosarcoma, its presentation and behaviour have been reported in the literature, and due to its bizarre behaviour it is a diagnostic challenge to pathologist and clinicians. Here we present a rare case of carcinosarcoma breast in a 55-year-old female who initially presented with cystic mass( lump) in right breast which was reported as organised hematoma on FNAC, on frozen section it was diagnosed as malignant cystic tumour. This was followed by mastectomy. Histopathology with immune markers, the case was diagnosed as metaplastic carcinoma with biphasic type called carcinosarcoma. The case merits presentation because of its rare presentation as cystic lesion and difficult to diagnose mainly due to sarcomatous elements. An accurate diagnosis of this aggressive tumour is essential in order to optimally tailor adjuvant therapy.
