Definition / General
  • 55 - 75% of primary gastrointestinal lymphomas are gastric
  • Lymphomas are 1 - 7% of gastric malignancies
  • Diffuse large B-cell lymphoma most common, then extranodal marginal zone (MALT) lymphoma
  • Most patients age 60+
  • Clinically resembles carcinoma, but usually better prognosis
  • Associated with erosion (61%), intestinal metaplasia (59%), H. pylori (57%), atrophy (37%), dysplasia (4%) (Arch Pathol Lab Med 2000;124:1628)
Micro Description
  • Diffuse large B-cell lymphoma generally resembles nodal disease
  • Features highly suggestive of low grade lymphoma versus inflammation are dense lymphoid infiltrates with either prominent lymphoepithelial lesions, moderate cytologic atypia or Dutcher bodies (Am J Surg Pathol 1990;14:1087)
