Uterine Lipoleiomyoma in the Context of Adenocarcinoma

Abstract

We describe a case of a 63-year-old woman referred to an oncologist for treatment of endometrial adenocarcinoma. A computed tomography scan revealed the incidental finding of a 11.5 × 10.5 × 9.0 cm myomatous mass in the uterine corpus adjacent to, yet uninvolved with, the adenocarcinoma. Histopathological analysis confirmed the mass to be a lipoleiomyoma, a rare single variant of lipoma. These fatty tumors present similar to leiomyomas and as such are generally not harmful; however, the potential exists for diagnostic confusion with other uterine tumors. This case serves to further illuminate the findings associated with these rare tumors.
