Amyloidosis is a disorder resulting from extracellular deposition of insoluble fibrils and causes dysfunction in many organs. Secondary amyloidosis, caused by chronic infectious and inflammatory disease, may involve the kidneys, liver, bone marrow and gastrointestinal tract. Involvement of the gastrointestinal tract is common and presents various symptoms according to location. Amyloidosis as a complication of Crohn's disease is a rare but serious complication that may worsen the prognosis. We report a case of gastrointestinal amyloidosis in a 59-year-old male patient with Crohn's disease that was diagnosed with an endoscopic forceps biopsy of the stomach, terminal ileum and colon.
