[Incidence of primary gastric lymphoma and H. pylori infection in the central zone of Asturias].
OBJECTIVE
We review our experience with primary gastric lymphomas type B of low (MALT) and high grade in a population of 366,635 people during 4 years and after performing 9,268 gastroscopies.


RESULTS
The incidence of these lymphomas in our medium is similar to that found in the world population. Possible disagreements among the biopsy histology and that of the subsequent gastrectomy samples is pointed out.


CONCLUSIONS
The frequency of H. pylori involvement in our primary gastric lymphomas is similar to that reported in the literature for the age of our patients, for the MALT lymphomas an well as for the type B high grade.
