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 6-mercaptopurine. to our best knowledge, this is the first reported case of secondary amyloidosis in a teenage iranian boy with crohn’s disease.
