Recurrent Obscure Gastrointestinal Bleeding in a Patient With Gastric Amyloid

A 68-year-old woman was evaluated for melena and anemia with a hemoglobin level of 7.5 g/dL. Eleven months previously, a colonoscopy was performed for iron-deficiency anemia and hematochezia, which showed erythema and friability of the rectal mucosa corresponding to reactive lymphoid aggregates on biopsy. A subsequent esophagogastroduodenoscopy performed 3 months later for dysphagia showed gastric mucosal erythema and chronic gastritis.
