原发性胃恶性淋巴瘤的胃镜诊断

目的 总结分析原发性胃恶性淋巴瘤（PGML）胃镜下特征及诊断要点，以提高胃镜时该病的诊断率。方法 对24例经病理确诊的PGML临床、胃镜及病理资料进行分析。结果 该组PGML患者临床症状无特异性。胃镜下主要表现为溃疡型15例，肿块型7例，弥漫漫润型2例，病变累及胃体14例，胃窭10例，多部位者8例。术前胃镜活检确诊者19例（79％）。结论 PGML胃镜下具有病变范围广、病灶多发、形态多样的特点。胃镜活检是确诊PGML的主要手段，提高对该病的警惕和认识，掌握胃镜下活检技巧，可提高胃镜对PGML的诊断率。

Gastroscopic diagnosis of primary gastric malignant lymphoma

Objective To study gastric gastroscopic features and main points of diagnosis of primary gastric malignant lymphoma(PGML), and to improve its diagnostic efficiency. Methods The clinical and endoscopic and histopathologic data of 24 patients with PGML diagnosed pathologically were reviewed and analyzed. Results The clinical appearance of PGML were not peculiar. Its main gastroscopic appearance was ulcerative lesions in 15, nodose lesions in 7 and infiltrating lesions in 2 patients. The lesions originated from body of stomach in 14 cases, antrum in 10 and multifoeal lesions were found in 8 instances. Endoscopic biopsies were diagnostic in 19 patients (79%). Concllusion Gastroscopic appearance of PGML were multiplicity and polymorphous and multifoeal lesions. Its diagnosis was mainly by the gastroscopy and biopsy. Heighten the awareness of PGML and improvement in the bioptic sampling technique can effectively improve the rate of confirmed diagnosis of PGML.
