Abstract:
Carcinosarcoma of the breast is an extremely rare and highly aggressive breast tumor.It has two distinct malignant cell lines involving epithelial (carcinomatous) and mesenchymal (sarcomatous) components. The literature on the topic is sparse. We report a rare case of carcinosarcoma of the breast containing a small fraction of a pancytokeratin positive sarcomatous-appearing cell population i.e. a metaplastic cell population. The patient was treated with a multidisciplinary approach.
