为近一步探讨胃原发性恶性淋巴瘤的发病机制．提高对胃原发性恶性淋巴瘤胃镜及病理表现的认识，对１０年间经胃镜活检诊断为胃恶性淋巴瘤的１９例，可疑胃恶性淋巴瘤、低分化癌、未分化癌、溃疡及淋巴组织明显增生的１２１例病理标本、临床资料进行回顾复习，最后确认有３８例符合胃恶性淋巴瘤的诊断标准。，胃镜下多形性、多灶性、弥漫性、范围广是其特征表现，而组织学上粘膜相关淋巴组织的特点对确诊本病有重要意义。
To further explore the pathogenesis of primary gastric lymphoma. Raise the awareness of gastroscopy and pathological features of primary gastric lymphoma, 19 cases of gastric malignant lymphoma diagnosed by endoscopic biopsy over 10 years, suspected gastric malignant lymphoma, poorly differentiated carcinoma, undifferentiated carcinoma, ulcer and lymphoid tissue The pathological specimens and clinical data of 121 cases with obvious hyperplasia were reviewed and reviewed. Finally, 38 cases were diagnosed as consistent with the diagnostic criteria of gastric malignant lymphoma. Gastroscopic polymorphism, multifocal, diffuse, and wide range are characteristic features, and the characteristics of histologically related mucosa-associated lymphoid tissues are of great significance for the diagnosis of this disease.
