[Primary malignant lymphoma of the stomach].
A malignant lymphoma (ML) was found in resected stomach and regional lymphnodes of a 62-year- old woman. The process looked like flattening of mucosal folds or slight map-like elevation of antral and pyloric mucosa. Tumorous foci were spread in submucosa, muscular layer and lymphatics of the stomach wall. Tumour histology equaled centrocytic follicular ML with lymphoepithelial lesions and many plasmacytes in gastric mucosa. Differential diagnosis of this peculiar type of ML which was defined by Isaacson et al., has to distinguish especially so called pseudolymphoma and immunocytoma as well as undifferentiated stomach carcinoma. A relatively favourable behaviour of this centrocytic ML gives reasons for separating it in a group of ML of mucosal lymphatic tissue.
