A 65-year-old woman with a history of treatment for splenic marginal zone B-cell lymphoma and gastric mucosa-associated lymphoid tissue (MALT) lymphoma underwent esophagogastroduodenoscopy. A reddish elevated lesion was found in the fundus of the stomach. On image-enhanced endoscopy, several findings, such as glandular structures of varying sizes suggesting well-differentiated adenocarcinoma, pruned blood vessels, and dilated blood vessels in deeper mucosa suggesting MALT lymphoma, were observed. The final pathological diagnosis after surgical resection was collision tumors of well-differentiated adenocarcinoma and MALT lymphoma. The features of both tumors could be observed simultaneously with image-enhanced endoscopy.
一位 65 岁女性，曾患有脾边缘区 B 细胞淋巴瘤和胃黏膜相关淋巴组织（MALT）淋巴瘤，接受了食管胃十二指肠镜检查。在胃底部发现一个红色隆起性病变。在增强内镜下，观察到一些表现，如大小不一的腺体结构提示分化良好的腺癌、修剪状血管和更深黏膜中的扩张血管提示 MALT 淋巴瘤。手术切除后的最终病理诊断为分化良好的腺癌和 MALT 淋巴瘤的碰撞肿瘤。两种肿瘤的特征都可以在增强内镜下同时观察到。
