A Case of Leiomyoma Originating from the Round Ligament of the Uterus Performed Laparoscopic Surgery

Abstract

A 42-year-old woman was admitted to our hospital because of a right groin mass, and underwent laparoscopic transabdominal preperitoneal repair with a diagnosis of right inguinal hernia. Intraabdominal observation revealed no hernia orifice. Preperitoneal dissection revealed a solid tumor arising from the right round ligament of uterus and growing into the inguinal canal. We made the diagnosis of a tumor originating from the round ligament of the uterus, resected the tumor and reinforced the posterior wall of the inguinal canal with a mesh. The histopathological diagnosis of the resected tumor was leiomyoma. Leiomyomas originating from the round ligament of the uterus are extremely rare, and so far no cases treated by laparoscopic surgery have been reported. Although it is rare, the tumor originating from the round ligament of the uterus should be considered when a groin mass is encountered in adult women.
