Synchronous endometrial carcinosarcoma and breast carcinoma: a case report.

The association of breast and uterine carcinoma has been demonstrated by many authors. However, these double primaries with endometrial cancer having pathologic features of a carcinosarcoma are a very rare phenomena. Moreover, most of the cases are related to the previous use of tamoxifen for the treatment of breast carcinoma. In the present study we describe a case of an endometrial carcinosarcoma and a synchronous adenocarcinoma of the breast.
