Endometriosis in the groin

Abstract

Recently we found one case of endometriosis in the extraperitoneal part of the round ligament (EERL). We found 30 cases previously described in the literature. A comparison showed that 90% were right-sided and often associated with an inguinal hernia. Fertility seemed to be below normal. In four of the cases a laporotomy was done. All had intraperitoneal endometriosis. In cases of EERL and claimed sterility therefore, the presence of intraperitoneal endometriosis should also be considered.

An atypical manifestation of inguinal endometriosis in the extra pelvic part of the round ligament: a case report

“…6 In our case, infiltration of the intraabdominal part was accompanying the round ligament into the inguinal canal, involving the extraperitoneal part. In 32% of the described cases, infiltration affected an inguinal hernia, occasionally, even after excluding the intraperitoneal endometriosis laparoscopically.…”

“…In 32% of the described cases, infiltration affected an inguinal hernia, occasionally, even after excluding the intraperitoneal endometriosis laparoscopically. 6,25 Nonetheless, in previous six cases the initial tentative diagnosis of inguinal hernia were reported, the confirmation of this diagnosis throughout the surgery was missing. 5 In all of these women, the endometriotic lesions were located in the extra-peritoneal portion of the round ligament, without any apparent spatial communication with the pelvis.…”

“…10 It is remarkable, that in most cases of the inguinal endometriosis extra-peritoneal part of the round ligament is affected. 6 Rarely, endometriosis also have been observed in inguinal hernial sacs in lymph nodes, in canal of Nuck or in regions associated with femoral vessels and femoral hernia. 2,3,24,27,28,32 Subsequent to extra-peritoneal manifestations of endometriosis, a simultaneous laparoscopy is strongly recommended, in order to exclude further expression of intraperitoneal endometriosis.…”

“…19 In the literature, it has also been reported that in 90% of the cases preferred manifestation of inguinal endometriosis involves the right groin. 6 Why this affection involves predominantly the right side of the groin is still undefinable. Furthermore, usually we inspect more right sided affection of the diaphragmatic endometriosis.…”

Endometriosis of the Inguinal Region, Case Report

“…These two interesting cases highlight the necessity to include endometriosis in the differential diagnosis of lump/mass in the groin in female patients [2].…”
