The incidence of intussusception and endometriosis of the appendix is estimated as 0.01%and 0.05%, respectively. But few cases have been reported in Japan. According to literature, only 5 cases of appendiceal intussusception associated with endometriosis, including our case, have been reported. Here we report the case of a 34-year-old female. She visited our hospital presenting with bloody stool and abdominal pain. She was diagnosed as having a submucosal tumor or a tumor of the appendix using colonofiberscopy. abdominal ultrasonography and computed tomography. At operation, intussusception of the appendix into the cecum was observed, and appendicecal resection was done. Histologically, appendiceal endometriosis and aappendiceal mucocele were diagnosed. Primary appendiceal intussusception by obstructing endometriosis may have led to secondary appendiceal mucocele.
