An Inguinal Lump, Please Put an Endometriosis Extra Pelvic on Your Diagnosis List : Cases Series of Deep Endometriosis

Abstract

Deep Endometriosis is usually found in the ovaries, peritoneum, gynecological organs and in the pouch of Douglas. We have reported 5 rare cases of extra-pelvic endometriosis from 2018-2023 on a patient who had endometriosis surgery and suffered from a mass in her inguinal area, and the symptoms were going up and down along with the menstrual cycle. An unclear mass which was hard and elastic in the right side of inguinal area with an average diameter of 22.2 cm2 at the bottom edge of the rectus abdominal muscle. The patient was then given 2mm Dienogest therapy for 180 days and the mass tended to enlarge so that it was decided to undergo surgery. The rare incidence of DE at inguinal is one of the considerations as a differential diagnosis for painful inguinal hernias. Collaboration and multidisciplinary approach are needed to understand better and to find appropriate therapy to prevent a recurrence.
