Abstract

Amyloidosis is a clinical entity that results from deposition of an extracellular protein material that causes disruption in normal architecture and impairs function of multiple organs and tissues.

Renal failure is the most common clinical presentation of AA, ranging from nephrotic syndrome and impaired renal function to renal failure, with a potential for high morbidity. The incidence of the association of secondary amyloidosis in patients with Crohn's disease has been reported to be 0.5%-8%. We present a case of a 39-year-old male patient diagnosed with Crohn's disease at age 21 and submitted to right hemicolectomy because of ileus 17 years before. Thereafter, he was treated with corticosteroids for 15 years and with azathioprine for a short period; in the last three years he was on therapy with mesalazine alone.
