gastric lymphoma

Oncology A diffuse lymphoma composed of monotonous mature or atypical lymphocytes, or of large lymphocytes Etiology GL, especially MALT lymphoma, is linked to H pylori infection; other causes of GL are speculative Clinical Epigastric pain, N&V, tarry stool, ↓ appetite, abdominal mass Prognosis 5/10-yr survivals–57%/46%, respectively. Note Histologic type, clinical stage, mode of therapy have little prognostic value. See Lymphoma, MALT lymphoma.

CLE criteria for gastric lymphoma were based on recent established findings as follows [10-12]: (1) darkened areas made up of small roundish cells of similar size and morphology for the mucosa-associated lymphoid tissue (MALT) lymphoma or larger roundish cells for diffuse large B-cell lymphoma (DLBCL); abnormal cells in a dense arrangement; (2) cellular infiltrates typically affecting but not limited to the lamina propria; (3) cellular invasion of various epithelial structures; (4) altered tissue morphology to complete loss of structural integrity of the epithelium.
