Endometriosis involving sites outside the pelvic cavity is a relatively uncommon occurrence and its frequency is cited as being less than one percent of all occurences of endometriosis. Sites previously reported in literature have described
involvement
of the extraperitoneal portion of the round ligament, the rectosigmoid, the appendix, and the ileum. Other more distal sites reported to have been found to have endometriosis lesions include the inguinal ligaments, the umbilicus, abdominal
incisional
wounds, thoracic lesions involving the pleura or diaphragm which may result in catamenial pneumothorax, the kidneys, and vulvar episiotomy wounds. Endometriosis have even been reported to occur in males.
In this presentation, three cases of endometriosis, two involving the vulvar area and one involving a Pfannenstiel incision wound, is presented with a review of the pertinent literature in order to discuss its etiology, pathology, diagnosis and
treatment.
