title: Benign heterologous tissue components associated with endometrial carcinoma.
abstract: Two cases of adenocarcinoma of the endometrium associated with benign mesenchymal tissues of adipose and osteoid type are presented. These components have a metaplastic or metamorphic, rather than neoplastic, origin. Heterologous elements associated with adenocarcinoma should not be mistaken for the more common mixed mesodermal müllerian tumors which have a different clinicopathologic behavior.
