title: [Regression of primary gastric lymphoma after treatment with ranitidine].
abstract: In a 60 years old patient affected by primary gastric MALT lymphoma stage IE, we observed a complete regression after aspecific treatment with ranitidine 150 mg x 2/day; after regression we treated the patient with anti-Helicobacter pylori therapy for 30 days. Nowadays, after 3 years of clinical and endoscopical follow-up we observe no relapse of disease. The elimination of antigenic stimulation of Helicobacter pylori, stopping T-lymphocytes' effect on B-lymphocytes, stopped neoplastic proliferation, causing the complete regression of neoplastic lesion. This clinical case, according to biological data about primary gastric lymphomas, suggests different ways of treatment for primary gastric lymphomas at the lowest stage of disease.
