　Inguinal endometriosis is rare and accounts for 0.3% to 0.6% of all cases of endometriosis. Although a few studies have described drug therapy for this condition, inguinal endometriosis is primarily treated surgically. We report a case of inguinal endometriosis in a patient who presented with a mass and menstruation-associated pain in the inguinal region. Dienogest administered as pharmacotherapy was ineffective, necessitating surgical management. The inguinal mass was percutaneously removed along with the round ligament after laparoscopic resection of the round ligament. Dienogest was administered postoperatively, and no recurrence was observed during follow-up. We present a case of inguinal endometriosis, together with a literature review on the surgical treatment of inguinal endometriosis with laparoscopy in Japan.
