Low-grade gastric mucosa associated lymphoid tissue (MALT) lymphoma has a broad spectrum of endoscopic presentations, which ranges from diffuse erosion to ulcerative mass. The bland appearance of this disease in some patients may reflect the early stage of the disease. We report 2 cases of low-grade gastric MALT lymphoma in which the endoscopic presentation consisted with normal appearing mucosa of the stomach. The patients were successfully treated with anti-Helicobacter pylori therapy. Endoscopy is useful to diagnose and follow up low-grade gastric MALT lymphoma. However, in the early stages of the disease, the histologic evaluation of biopsy specimens obtained from all gastric areas can be the more reliable diagnostic procedure to detect this neoplasm.
