A rare inguinal mass: Round ligament leiomyoma.

Introduction: Leiomyoma of the round ligament is a rare condition and usually appears like an inguinal hernia.

Presentation Of Case: We report a case of a 40 year-old women found to have an inguinal mass which it was finally diagnosed as leiomyoma. The patient was admitted to our hospital with a history of painless groin mass. The mass was thought to be irreducible inguinal hernia. Surgical exploration demonstrated a round ligament leiomyoma.

Discussion: A smooth muscle tumor in the round ligament of the uterus in the inguinal region is a rare entity and can be mistaken for an irreducible inguinal hernia. It is a rare condition occurring predominantly in premenopausal middle-aged women. Abdominal, inguinal, and vulvar locations have been described. Surgical excision is the curative treatment.

Conclusion: Leiomyoma of the round ligament should be entertained as a possible etiology of inguinal mass.
