We have examined 1400 gastric biopsy specimens using classic morphological and immunohistochemical methods. Immunohistochemistry was performed using monoclonal antibodies against CD-20, CD-3, Bcl-2, EMA, CD-30 and Ki-67. A total of 105 cases were diagnosed as MALT lymphoma. We have analyzed age and epidemiological characteristics of these MALT lymphomas. Based on the received data we have concluded that MALT lymphomas are not rare entity in Georgia, particularly, this lymphomas consists 9, 0% of a total gastric cancer cases and 80% of B-lymphomas.
