Abstract

The patient was a 54-year-old male who visited our department without any symp-toms after the elevated lesion of lesser curvature of antrum was noted in a mass X-ray survey of the stomach. Gastroendoscopy revealed a flat lesion forming a white color zone on the anterior wall of the anglarnotch. In biopsies from the white color zone, lympho-plasmacytoid cells producing monoclonal IgM/λ were diffusely observed in the lamina propria mucosae, leading to diagnosis of plasmacytoma. Similar changes were also observed in the lamina propria mucosae of the resected specimen. About 100 cases of plasmacytoma of the stomach have been reported abroad, and 38 cases including ours in Japan.
