Non-Hodgkin´s lymphomas (NHL) of the gastrointestinal (GI) tract are the most common extra nodal lymphomas. They represent between 30% to 70% of all extra nodal lymphomas and constitute a heterogeneous group of tumors with different clinical and pathological features. The stomach is predominantly involved. MALT type lymphomas are the most frequent low grade non-Hodgkin´s lymphomas encountered in the GI tract. They account for 40% of all primary gastric lymphomas and remain, in the majority of cases, localized for a prolonged period of time without therapy. Aim: To evaluate the epidemiology of gastrointestinal lymphomas in our Hospital. Patients and Methods: Retrospective analysis of patientÊs recorders performed at the Hospital Militar "Dr. Carlos Arvelo", Caracas, that had the diagnosis of gastrointestinal lymphoma. Results Clinical and histopathologjcal data from 20 patients presenting with GI-NHL treated from 2003 until 2008, were reviewed. 15 men, 5 women with an age range between 23 and 64 years old. Of these, 14 (70%) presented with limited disease (stage I and II), while 6 patients were found to have disease involvement of other abdominal organs (i.e., liver, pancreas, spleen, duodenum) or more than one gastrointestinal site and were therefore classified as stage IV. 11 patients presented with lymphoma in the stomach, 2 pancreatic, 1 in liver, spleen and lumbar vertebrae, 1 in the small intestine and 4 in the large bowel, while in 5 cases multiple localizations of the gastrointestinal tract were documented. Abdominal pain, gastrointestinal bleeding, weighs loose were the main presenting symptom.
