Parasitic leiomyoma. A rare cause of inguinal mass in females.

Leiomyoma of the uterus is a common tumor during the reproductive age of females. It is classified as intrauterine and extrauterine. Extrauterine leiomyomas may occur without a concurrent uterine pathology. Different growth patterns have been described, like retroperitoneal and parasitic growth. We report a case of a 28-year-old female who was found to have inguinal mass, and it was finally diagnosed as parasitic leiomyoma. The mass was coming through the posterior inguinal wall into the subcutaneous region, like a direct inguinal hernia. She underwent excision of the mass, and repair of posterior inguinal wall. Parasitic leiomyoma can be a rare cause of inguinal swelling. When diagnosed, surgical excision is the treatment of choice.
