Leiomyoma of the Broad Ligament in an Obturator Hernia Presenting as a Lump in the Groin

Obturator hernia is an infrequent entity. About 550 cases have been reported in the English literature1,2 since it was first described by Arnaud de Ronsil in 1724. The commonest structure that herniates into an obturator hernia sac is small intestine3-5. Cases have been reported of bladder, fallopian tube, ovary, omentum, appendix, caecum and uterus3,5-7. No previous report of a benign tumour of the broad ligament herniating into an obturator hernia sac, and presenting as a lump in the femoral triangle, has been traced.
