#### **2.1 Materials and methods**

The study was performed on gastrobiopsies from 115 patients with lymphoid cell infiltration of gastric mucosa including 71 patients with MALT lymphoma of the stomach, 23 patients with reactive (nontumor) lymphoid infiltrations, 21 patients with non MALT type peripheral small B-cell gastric lymphomas (cytological grade I or I–II FL, MCL), Burkitt's lymphoma (BL). There were 48 males and 67 females in the study group. The study was carried out using histological and immunohistochemical methods.
