Case report of two primary tumors: mullerian adenosarcoma and endometrial adenocarcinoma.

: A rare case of two concomitant primary uterine neoplasmas in a 64-year-old patient who had received conjugated estrogens for the 3 preceding years is presented. Mullerian adenosarcoma, heterologous type, with stromal components suggestive of rhabdomyosarcoma, and adenocarcinoma of endometrium, were localized in different sites of the endometrium with no intermingling between them (combination tumor). The diagnostic and therapeutic problems are discussed.
