A CASE OF SUPERFICIAL SPREADING MALT LYMPHOMA OF THE STOMACH PRESENTING VARIED ENDOSCOPIC FINDINGS

Abstract

The patient was a 36-year-old man with a chief complaint of nausea. Upper Gl endoscopy revealed a lesion showing marked convexity and concavity with irregular redness and discoloration on the posterior wall from the lower part of the gastric body to the antrum. On histological examination of biopsy specimen obtained from the area, the lesion was considered to be a MALT lymphoma which arose by formation of lymphoepithelial lesion through infiltration of the glandular epithelium. Endoscopic examination one month later revealed that the lesion presented a shallow irregular ulcer. This case was considered to be a MALT lymphoma at its early stage.
