Endometriosis is the presence of endometrial glands and stroma outside the uterine cavity. Although it is common in women in the reproductive age, intestinal endometriosis is extremely rare and may lead to serious clinical problems. In this article, we present two rare cases of endometriosis localized in the sigmoid colon lumen. The first case is a 45 year-old female complaining of rectal bleeding for 6 months. A polypoid lesion with suspicion of malignancy, 3-4 cm in size was identified at colonoscopy. Laparoscopic anterior resection was performed since it was not suitable for colonoscopic polypectomy. The pathology examination revealed extragenital endometriosis. The second case is a 36 year-old female admitted for lower abdominal pain and rectal bleeding for the last 3 months. She was diagnosed with sigmoid diverticulitis. The patient’s symptoms regressed with medical treatment, but due to early and multiple recurrent episodes it was decided to perform an elective laparoscopic anterior resection. The pathology report stated diverticulosis coli and intraluminal endometriosis. Intestinal endometriosis should be considered as part of the differential diagnosis in female patients of the reproductive age who present with constipation, gastrointestinal bleeding, nausea, vomiting, cramp-like abdominal pain, diarrhea and pelvic pain. In these patients, resection and anastomosis of the effected bowel segment is accepted as the choice of treatment.
