RESUMO
Tumors of the round ligament rarely happen; leiomyomas are considered the most common. Round ligament leiomyomas are benign tumors mimicking inguinal hernia, lymph nodes, or other inguinal masses. They are usually asymptomatic and take place in premenopausal female patients. This paper will present a case of a postmenopausal female patient who presented to our outpatient surgical clinic complaining of a right groin mass for 3 months. She was clinically diagnosed as a case of an irreducible inguinal hernia. After investigations, it turned out to be a round ligament leiomyoma, confirmed by the histopathological examination. There are broad differential diagnoses of inguinal masses. Although imaging exams could help diagnose leiomyomas, surgical excision followed by histopathological assessment is the best to confirm the diagnoses.
