RESUMO
We report 65 cases of MALT gastric lymphomas. HP was looked for with Giemsa and Whartin Starry stains. Immunohistochemistry was done with PAP method. Anti-HP treatment was used in 9 cases. 38 were of low grade of malignancy, 23 were high grade, 4 were high grade with a low grads component. The mean age was 51.5 years, the sex ratio 1.5. Epigastric pain was the most frequent feature [87.7 percent of cases]. Endoscopically, low grade lymphomas presented as unique or multiple ulcerations [55.3 percent of cases] with antral localization [52.6 percent of cases]. 60 percent of our patients were stage IE, of which 61 percent had low grade lymphoma, 18 percent were at stage 112E, 10 percent at stage III and 10 percent at stage IV. From 23 operated patients, 29 percent had early lymphoma which was low grads malignant in 71.5 percent of cases, and 71 percent had lymphomas which were wi-dely spread beyond the submucosa. HP was found in 63 percent of cases. Histologic regression of two early lymphomas of low grade malignancy was achieved after HP eradication
