[Plasmacytoma of the stomach (author's transl)]

Over a period of two years, enlarged folds in the gastric antrum were found on several occasions, during barium meals, in a 50-year old patient. On gastroscopy and biopsy, the diagnosis of superficial gastritis was made. Six and a half years later the radiological examination, gastroscopy, and biopsy were repeated with suspicion of a malignant tumour. Following histological examination of the resected specimen, the diagnosis of gastric plasmacytoma was made. The features of this rare contition are described and the literature is reviewed.
