Two types tumor could be differentiated by their appearance on endoscopy (two had both types). An exophytic type (n = 24) was easily recognized as malignancy confirmed biopsy (mean 1.2 endoscopic-bioptic examinations). It classified according to Palmer classification; 50 % low-grade malignancies high-grade malignancies. Resection 17) showed wall penetration beyond muscularis propria 70 %. infiltrative 44) difficult diagnose means 2.9 examinations); one case a histological only established surgery. A classification system suggested for this (I - elevated, II flat, III cavitated). Most these (77 %), limited submucosa (79 34 resected cases). concluded that attention should paid especially gastric lymphoma differentiate from other conditions such ulcers erosions, but most often found at an early stage has better prognosis. Complete resection (R0) achieved 49 51 undergoing surgery (96 %). In curatively (stage IE IIE) follow-up data available: 5-year survival rate 81 lymphoma-related 88
