Incidental Finding of a Lipoleiomyoma During Robotic Inguinal Hernia Repair: A Case Report.

Abstract

Lipoleiomyomas are rare, fatty variants of leiomyomas (commonly referred to as fibroid), which are frequently found in the uterine corpus and cervix. Here, we present a case of a robotic inguinal hernia repair with resection of an incidental lipoleiomyoma. A 74-year-old woman presented to the office with complaints of pain and a palpable mass in the right inguinal region. Physical examination revealed tender, moderate-to-large bilateral inguinal hernias. Robotic bilateral inguinal hernia repair with mesh was performed. Intraoperatively, a mass measuring 4 × 3 cm was noted near the round ligament of the uterus. The mass was encapsulated without invading any surrounding structures. The mass was resected and sent to the histopathology department. The pathological evaluation identified a leiomyoma filled with mature adipocytes, compatible with the diagnosis of an extrauterine lipoleiomyoma. Lipoleiomyoma incidentally found in the inguinal canal is extremely rare. The medical literature regarding this incidental finding is limited. Resection of the mass was easily performed using the same robotic instruments as used for the inguinal hernia repair.
