Abstract

A 59-year-old man was hospitalized due to a complaint of intermittent upper abdominal distension that persisted over the duration of 2 years. Endoscopy revealed a ﬂ at depressed (type 0-IIa þ IIc) and whitish lesion approximately 2.0 (cid:2) 2.5cm in size in the anterior wall of the antrum ( ► Fig. 1 ). Reddish spots were sparsely distributed in the mucosa of the lesion. No gastric mucosa atrophy was observed. Magnifying endoscopy with narrow-band imaging (NBI) showed a nice demarcation line between the lesion and the surrounding mucosa. The morphology of the lesion surface was irregular, with minimal residual glandular fossa, as well as damage and loss of the gastric pit structure, suggesting destruction of glands. The microvessels were bifurcated, sparse, and tortuous; “ tree like appearance ” of the abnormal vessels can be seen in the NBI ( ► Fig. 2 ). The 20-MHz mini-probe endoscopic ultrasound showed that all layers of the gastric wall were intact without abnormal echo ( ► Fig. 3 ). Histopathological examination of the biopsy specimen revealed a dense small-to-medium-sized lymphoid in ﬁ ltration. Immunohistochemistry

具有特殊内镜形态的胃黏膜相关淋巴组织淋巴瘤病例

一名59岁的男子因间歇性上腹部胀痛住院治疗，该症状持续了2年之久。内镜检查发现，咽鼓管前壁有一个约 2.0 (cid:2) 2.5 厘米大小的凹陷性（0-IIa þ IIc 型）白色病灶（► 图 1）。病变部位的粘膜上稀疏分布着淡红色斑点。未观察到胃黏膜萎缩。放大内镜和窄带成像（NBI）显示病灶和周围粘膜之间有一条清晰的分界线。病灶表面形态不规则，腺窝残留极少，胃凹陷结构受损和消失，提示腺体已被破坏。微血管分叉、稀疏且迂曲；在 NBI 中可以看到异常血管的 "树状外观"（► 图 2）。20 兆赫微型探头内镜超声显示胃壁各层完整，无异常回声（► 图 3）。活检标本的组织病理学检查显示有密集的中小型淋巴细胞。免疫组化
