Cervical adenocarcinoma and adenomatoid tumor of the uterus; A rare coexisting finding and review of the literature

Genital origin adenocarcinomas with coexisting uterine adenomatoid tumors are very rare with only four published cases in the literature. We report a case of adenomatoid tumor of the uterus that was found incidentally during treatment of cervical adenocarcinoma. Although adenomatoid tumors may cause a differential diagnostic problem, in our case the hematoxylin-eosin histological and immunhistochemical studies confirmed mesothelial phenotype of tumor and these also helped in differentiating an adenomatoid tumor from the carcinomatous myometrial invasion. Adenomatoid tumors are easily recognizable benign pathologies. An incidental finding of adenomatoid tumors accompanied by adenocarcinoma of the endometrium or cervix should always be considered.
