We encountered a case of intestinal endometriosis with difficulty in preoperative diagnosis. Here we report the case with some literature review. The patient was a 49-year-old woman. She visited a nearby doctor due to the positive result of fecal occult blood test at a medical check-up. She was referred to our department for detailed examination and received treatment because a type 1 tumor was suspected in the rectum Rs by lower gastrointestinal endoscopy. Three times of endoscopic exams performed in our hospital revealed that submucosal tumor-like appearance was seen in the rectum, however biopsy did not lead to definitive diagnosis. Since the possibility of malignancy could not be denied and the patient strongly desired to receive operation, laparoscopic high anterior resection was performed. In the intraoperative findings, the pelvic cavity was white tone and the endometrium was firmly adhered to the rectum. The resected specimen showed a submucosal tumor, and intestinal endometriosis was confirmed with pathological diagnosis.
