胃恶性淋巴瘤发生率较低,约占胃恶性肿瘤的0.5～3%。临床上需与胃癌及其他肉瘤鉴别。近年发展的超声内镜(EUS)与以往一般内镜不同,在描绘胃壁层结构的同时,亦能发现病变内部结构。因此,EUS尤对具有粘膜下肿瘤特性的胃恶性淋巴瘤是有效的检查方法,并能对肿瘤浸润程度作出诊断。作者收集4例胃恶性淋巴瘤,男女各2例,年龄43～77岁(平均63.8岁)。镜下分型:决溃型3例,溃疡型1例(佐野分类法),组织学分型均为非何杰金氏型弥漫性淋巴瘤(LSG分类法)。决溃型中2例为中细胞型,1例大细胞型,溃疡型为小细胞型。作者还收集22例胃癌患者作为比较,其中男14例,女8
The incidence of gastric lymphoma is relatively low, accounting for approximately 0.5 to 3% of gastric malignancy. Clinical need to identify with gastric cancer and other sarcomas. In recent years, the development of ultrasound endoscopy (EUS) is different from the previous general endoscopy. While depicting the structure of the stomach wall, it can also find the internal structure of the lesion. Therefore, EUS is particularly effective in the detection of gastric malignant lymphomas with submucosal tumor characteristics, and can diagnose the degree of tumor invasion. The authors collected 4 cases of gastric lymphoma, 2 cases for men and women, aged 43 to 77 years (average 63.8 years). Microscopic classification: 3 cases of collapse type, 1 case of ulcer type (Sano classification), and non-Hodgkin type diffuse lymphoma (LSG classification). In the collapse type, 2 cases were of the intermediate cell type, 1 case of the large cell type, and the ulcer type of the small cell type. The author also collected 22 patients with gastric cancer as a comparison, including 14 males and 8 females.
