Eighteen patients with primary gastric malignant lymphoma were compared retrospectively with an age- and sex-matched group of patients with gastric cancer. It was found that a correct preoperative diagnosis was established in 8 out of 18 lymphoma patients (44%). Of the remaining patients eight were preoperatively diagnosed as cancers and two as benign ulcers. Malignancy was not suggested by biopsy or cytology in a total of six lymphoma patients. There was no difference as regards the size of the gastric lesion between the groups. A diffuse involvement of the stomach was found only in lymphoma patients. Furthermore, lymphoma patients often showed superficial stellate ulcers and a sharp margin between the lesion and the normal mucosa. It is suggested that these findings should make the investigator aware of the possibility of a gastric lymphoma. When this diagnosis is considered, great importance should be attached to obtaining large biopsies which possibly allow a correct preoperative diagnosis more often.
对18例原发性胃恶性淋巴瘤患者与年龄及性别相匹配的胃癌患者组进行回顾性比较。结果发现，18例淋巴瘤患者中有8例（44%）术前诊断正确。其余患者中，8例术前被诊断为癌症，2例被诊断为良性溃疡。共有6例淋巴瘤患者的活检或细胞学检查未提示恶性病变。两组胃病变大小无差异。仅在淋巴瘤患者中发现胃弥漫性受累。此外，淋巴瘤患者常表现为浅表星状溃疡，病变与正常黏膜之间边界清晰。提示这些发现应使研究者意识到胃淋巴瘤的可能性。当考虑这一诊断时，应高度重视获取大块活检组织，这可能更常使术前诊断正确。
