title: Gastrointestinal amyloidosis presenting with multiple episodes of gastrointestinal bleeding.
abstract: Amyloidosis is characterized by the extracellular deposition of amyloid protein in various organs. Gastrointestinal involvement in amyloidosis is common, but a diagnosis of amyloidosis is often delayed. Severe gastrointestinal hemorrhage in amyloidosis is rare but can be fatal in some cases. We experienced a case of a 49-year-old man who presented with recurrent massive hematochezia. Although embolization was performed eight times for bleeding from different sites of the small intestine, hematochezia did not cease. We report the case, with a review of the literature.
