title: Large ileocecal submucosal lipoma presenting as hematochezia, a case report and review of literature.
abstract: BACKGROUND
  Colonic lipomas are rare subepithelial benign tumors affecting mainly middle-aged women. They are usually asymptomatic and, hence, are discovered incidentally on autopsy, surgery, or colonoscopy. There is a wide range of presentations like abdominal pain, bleeding per rectum, intussusception, etc. The latter picture constitutes the usual presentation of an ileocecal lipoma. Only few cases of ileocecal lipomas presenting as lower GI bleeding have been reported in the literature.
  
  
  METHODS
  We present a case of an adult female patient who was admitted to our institution complaining of hematochezia and right lower quadrant pain. She was found to have chronic anemia. She was investigated by CT scan of the abdomen & pelvis and by colonoscopy which showed a fungating, submucosal mass with ulcerated base near the ileocecal valve. She underwent a colonic resection. The pathology came out as a submucosal benign pedunculated ileocecal lipoma.
  
  
  CONCLUSIONS
  Colonic lipomas represent 4% of benign lesions of the gastrointestinal tract. They are usually asymptomatic hence are often discovered incidentally on colonoscopy, surgery or autopsy. The definitive diagnosis is made by pathological evaluation. Colonic lipomas are usually treated if they are symptomatic or there is any suspicion of malignancy. The treatment modalities include endoscopic and surgical resection.
  
  
  CONCLUSIONS
  We, hereby, describe a case of benign ileocecal lipoma that presented with hematochezia which is an unusual presentation. Also, there is a great controversy regarding the treatment of colonic lipomas. In this article, we tried to answer several questions concerning the management of ileocecal lipomas.
