Extraperitoneal inguinal endometriosis.

Abstract

Two instances of extraperitoneal inguinal endometriosis are presented with a review of the previous reports of proven diagnosis. A high index of suspicion is needed to avoid needless prolonged observation. The diagnosis must be considered in any woman of childbearing age especially if the groin mass is associated with menstrual variability in size and in tenderness of the mass. Excision is curative and should result in permanent relief of pain.
