Large Uterine Angiolipoleiomyoma Masquerading as an Ovarian Tumor: A Case Report

Abstract

Angiolipoleiomyoma (ALLM) is a rare benign mesenchymal tumor that primarily arises in the skin and kidney, and less frequently in the uterus. The present case may represent the largest reported uterine mass described as ALLM. We present a case of a 52‐year‐old woman with abdominal fullness and an irregular menstrual cycle having a large cystic abdominopelvic mass initially masquerading as a large ovarian tumor. Following successful tumor resection and subsequent histopathological and immunohistochemical analysis, a definitive diagnosis of uterine ALLM was established. This case shows that uterine ALLM can present with nonspecific clinical symptoms and radiologic features that mimic other pelvic pathologies, and should be considered in the differential diagnosis when evaluating pelvic masses in female patients.
