IntroductionInflammatory myofibroblastic tumor is a very rare benign tumor in children that mimics malignant tumors in its aggressiveness locally and by the possibility of recurrence after surgical resection, and causing anemia of chronic disease, which is a decrease in hemoglobin 1 to 2 g/dL below normal level in a patient with chronic illness.Case presentationA 32-month-old boy from Libya presented with microcytic hypochromic anemia. He had been treated in three countries and five centers without response to medical therapy. He was investigated at our center and found to have a mass in the colon causing intermittent intussusception and bleeding. He was treated surgically, and his condition improved dramatically. The pathology report proved a diagnosis of inflammatory myofibroblastic tumor.ConclusionWe report a case of an unusual tumor of the gastrointestinal tract causing chronic anemia not responding to medical treatment, and discuss the characteristics of inflammatory myofibroblastic tumor. In our case, we stress the involvement of a multidisciplinary team in treating such a patient who presents with common symptoms and signs but in whom there has been no response to any of the measures and treatment protocols.

Vitamin B12 malabsorption in the ileum has been postulated as the underlying cause of the Imerslund-Grasbeck syndrome comprising megaloblastic anemia, proteinuria, and multiple neurological abnormalities. A young Saudi child with spasticity, truncal ataxia, cerebral atrophy, megaloblastic anaemia and proteinuria is described. Replacement therapy with parenteral vitamin B12 resulted in the complete resolution of his neurological findings and brain atrophy.
