Abstract

Extraperitoneal inguinal endometriosis often presents as an inguinal mass in women of reproductive age, Approximately 40 cases of inguinal endometriosis have been documented in the sutgical and gynecological literature. The overall incidence is in the range of 0.4% of patients with endometriosis. The right side is much more commonly involved than the left (almost 90% of the time in one series of 23 patients), and rarely is the condition bilateral. The most frequent complaint of patients with inguinal endometriosis is an inguinal mass, followed by pain and enlargement of the mass near menstruation. Authors have experienced two cases of endometriosis of the extraperitoneal portion of the round ligament of uterus and report with a brief literature review.
