  • Abstract
  • Look Inside

 A 39-years-old female was refered to our hospital, because of malignant lymphoma of the stomach suspected endoscopically and histologically by another hospital. Our initial endoscopic examination also revealed an irregular shaped and shallow ulcerative lesion in the posterior wall of gastric antrum, strongly suggested malignant lymphoma, and histological examination of biopsy specimens revealed low-grade MALT (mucosa-associated lymphoid tissue) lymphoma. Helicobacter pylori (H.pylori) infection was also detected histopathologically and serologically. After the successful eradication of H.pylori, the ulcerative lesion was healed, and showed a whitish mucosal area with coarse surface and uncertain border. Histological findings of biopsy specimens became unable to indicate MALT lymphoma cells. And during four years observation period after the eradication, endoscopic findings have been almost stationary, and no evidence of MALT lymphoma has been detected histologically.
