INTRODUCTION: Intussusception occurs when a proximal segment of bowel telescopes into the lumen of the adjacent distal segment. It is common in children being usually idiophatic, in contrast to adolescents and adults, who have a demonstrable etiology in most cases. Intestinal lymphoma is an unusual cause of intussusception in adolescents and adults. CASE REPORT: A 16 year-old male presented with right lower quadrant abdominal pain lasting for 36 hours, with vomiting and bloody stool. Physical examination was unremarkable except for a palpable mass at the right lower quadrant. Abdominal sonography revealed ileocecal intussusception. Colonoscopy showed a protruding mass from the orifice of ileocecal valve which was reduced, and the patient had full withdrawal of symptoms. Three weeks later, the patient came back to our hospital with recurrent symptoms. Laparotomy was performed and a polypoid mass was noted at the terminal ileum with intussusception into the cecum. A right hemicolectomy was performed. After pathologic examination and tumor staging, a primary Burkitt lymphoma of the distal ileum was diagnosed. Postoperative convalescence was uneventful and the patient was referred to adjuvant chemotherapy.
