Abstract
- Amyloidosis is a disorder of protein metabolism that leads to extracellular deposition of amyloid in tissues and organs. Multiple organ dysfunction can be induced by deposition of amyloid. Diagnosis is established by histologic demonstration of amyloid protein in involved tissue using Congo red staining. A 72 year-old woman was admitted due to mild abdominal pain, diarrhea and hematochezia. Duodenoscopic and colonoscopic findings were nonspecific, however, multiple biopsies showed amyloid deposits characterized by green birefringence under polarized light. The findings of small bowel series and abdominal CT were compatible with amyloidosis. We experienced a case of amyloidosis with involvement of the whole bowel.
