Abstract

A few cases of multiple myeloma with gastrointestinal bleeding have been reported, but hematemesis is rarely encountered as an initial symptom of multiple myeloma. Here we report a case of multiple myeloma with an initial symptom of hematemesis. Gastroscopy revealed ulceration in the angulus of the stomach. Colonoscopy revealed many ulcers in the ascending colon. A definite diagnosis of gastrointestinal amyloidosis was made using tissue biopsy. A definite diagnosis of multiple myeloma was made using bone marrow puncture. Hematemesis may be an initial symptom of multiple myeloma. A diagnosis of amyloidosis-induced hematemesis should be considered in patients with multiple myeloma.
