Multiple, Large Colonic Xanthomas Presenting as Intestinal Obstruction.

Gastrointestinal (GI) xanthomas are rare entities found incidentally on endoscopy. There have been only a few cases where they presented with symptoms of bowel obstruction. We present a case of an 89-year-old woman with a history of short-gut syndrome due to partial colectomy who had multiple admissions with recurrent nausea/vomiting, abdominal distension, and bloating. She was found to have multiple, large, mass-like xanthomas in the rectosigmoid colon. The unusual location, mass-like lesions, and large size led to luminal narrowing causing the patient to have obstructive symptoms, which is a very unusual presentation of colonic xanthomas as most are discovered incidentally.
