Primitive Gastric Lymphoma - a Series of 3 Cases

Abstract

The Primitive Gastric Lymphoma represents the extra-ganglionic non-Hodgkin lymphoma most frequently and comprises a large spectrum, ranging from the mucosa-associated lymphoid tissue (MALT) lymphoma to aggressive diffuse large B-cell lymphoma. The Primitive Gastric Lymphoma is a rare tumor, with an occurrence ranging from 4% to 20% of non-Hodgkin lymphomas and approximatively 5% of primary gastric neoplasms. The chronic gastritis secondary to the infection with Helicobacter pylori was considered a major predisposing factor for MALT lymphoma. The clinical evolution and the prognosis of this disease depend on the subtype and histopathological stage at the moment of the diagnosis. Due to its rarity, many aspects of this neoplasm remain still controversial.
