The authors report a case of beta-thalassemia/hemoglobin E disease with extramedullary haematopoietic tumor which developed at the small intestine and caused intussusception. A 7 year-old boy with homozygous beta-thalassemia/hemoglobin E presented with recurrent abdominal pain. The abdominal ultrasonography showed ileo-ileal intussusception with a solid mass as the leading point. Resection of the ileal segment was performed. Pathological examination revealed an extramedullary haematopoietic tumor forming an intraluminal polypoid mass, being the leading point of the intussusception. Extramedullary haematopoiesis in the intestinal tract is rare. To our knowledge, this is the first case of extramedullary haematopoietic tumor that produced intussusception of the small intestine in a beta-thalassemia/hemoglobin E patient.
