N2 - A woman in her 70s was diagnosed with a protruding mucosa-associated lymphoid tissue (MALT) lymphoma during a secondary health examination. After eradication of Helicobacter pylori, a biopsy revealed gastric follicular lymphoma (FL) and the lesion was still protruding one year later. 18F-fluorodeoxyglucose positron emission tomography showed focal nodular hypermetabolic activity, suggesting that FL may have transformed into a diffuse large B-cell lymphoma. Upper gastrointestinal endoscopy, colonoscopy, and capsule endoscopy showed no other lesions in the gastrointestinal tract, and bone marrow biopsy showed no permeation into the marrow. Therefore, this lesion, which appeared as a submucosal tumor, was limited to the stomach. Laparoscopy and endoscopy cooperative surgery was performed, because it allows for correct pathological diagnosis while removing only a minimal portion of the stomach wall. Histological findings showed follicular structures consisting of abnormal lymphoid cells. Immunohistochemical analysis revealed that neoplastic cells were positive for CD20, CD79a, Bcl-2, CD10, and c-MYC, but negative for CD3, CD5, and cyclin D1. Finally, we diagnosed this lesion as a primary gastric FL.
