title: [Extranodal lymphomas of the gastrointestinal tract. Retrospective study of a six year period].
abstract: BACKGROUND
  We present a six year study (from 1998-2003 year) concerning Non-Hodgkin's lymphomas originating from the gastrointestinal tract according to the classification of WHO (1997).
  
  
  RESULTS
  For the mentioned period in the University Hospital "Sveti Georgi" are diagnosed 22 cases of extranodal Non-Hodgkin's lymphomas of the gastrointestinal tract; 9 (40.9%) of them originated from lymph nodes of Valdier, 1 (4.5%)--from parotid gland, 6 (27.3%)--from stomach, 4 (18.2%) from large intestine and 2 (9.1%) cases from the small intestine. The ratio men/women is equal, and the age is between 20 to 84 years. All the lymphomas were B-cells type; in 6 cases they are MALT lymphomas, and in the rest of the cases--diffuse large cell B-cell type Non-Hodgkin's lymphomas.
  
  
  CONCLUSIONS
  In our investigation all Non-Hodgkin's lymphomas of the gastrointestinal tract are of B-cell type. Obviously their diagnosis is being late; probably because diffuse large cell B-cell type Non-Hodgkin's lymphomas are the predominant type.
