Abstract excerpt
The histogenesis of carcinosarcomas is controversial, specifically with respect to clonality and cell of origin. To answer these questions, tumor cells from both epithelial and spindle-cell components were microdissected from three cases each of mammary carcinosarcoma and its postulated precursor, carcinoma with spindle-cell metaplasia. Clonality was assessed using the principle of X chromosome inactivation. Loss...
