A CASE OF PLASMACYTOMA WITH AMYLOID DEPOSITS OF THE STOMACH

Abstract

The patients was 49-year-old man. Endoscopic examination showed a diffuse elevatedlesion with irregular ulcer at the greater curvature of the gastric anglus in September 1991.With the histologic findings of biopsy specimens, we made a diagnosis of localized gastricamyloidosis. In October 1993, this lesion was re-diagnosed as gastric plasmacytoma withendoscopic biopsy, and total gastrectomy with splenectomy was performed in May 1994.The tumor was histopathologically gastric plasmacytoma and immunahistochemical studyrevealed to be classified in IgA/ κ type. A part of the turner and amyloid deposits extendedto the submucosal layer. This case suggests the possibility of the association betweengastric plasmacytoma and amyloid production.
