Massive gastrointestinal hemorrhage in a case of amyloidosis secondary to rheumatoid arthritis.

A case of a 60-year-old woman with secondary gastrointestinal amyloidosis to rheumatoid arthritis is reported. Biopsy findings in the mucosa of the stomach and lower gastrointestinal tract revealed amyloidosis. Endoscopic examination of the lower gastrointestinal tract revealed multiple nodular elevations. The patient showed massive melena. Emergency angiography was performed and an extravasation was found at branches of the jejunal artery. Embolization was performed and this lead to a good prognosis. Patients with massive hemorrhages following gastrointestinal amyloidosis generally have a poorer prognosis. Embolotherapy performed for the present case might represent an effective therapeutic method for gastrointestinal hemorrhage in gastrointestinal amyloidosis.
