Systemic Amyloidosis in a Teenage Boy with Inflammatory Bowel Disease

Systemic amyloidosis is a very rare complication of inflammatory bowel disease (IBD). The reported cases of secondary amyloidosis in children with IBD are much fewer than those reported in adults. Herein, a teenage boy with Crohn’s disease is presented who developed nephrotic syndrome due to renal involvement secondary to amyloidosis, whereas the patient was under treatment with corticosteroid and 6mercaptopurine. To our best knowledge, this is the first reported case of secondary amyloidosis in a teenage Iranian boy with Crohn’s disease.
