# 异位组织(Ectopic Tissue) - 器官 / 系统:前胃 / 消化系统(stomach-forestomach / alimentary-system) - NTP 数据编号:ntp-0209 - 规范 URL:https://www.labsmart.cn/ntp/stomach-forestomach-ectopic-tissue.html - 中文图谱总页锚点:https://www.labsmart.cn/ntp-atlas.html#stomach-forestomach-ectopic-tissue - 原始出处:https://ntp.niehs.nih.gov/atlas/nnl/alimentary-system/stomach-forestomach/EctopicTissue - 授权:美国联邦政府作品,公有领域;引用请标注 NTP Nonneoplastic Lesion Atlas - 适用说明:仅供科研使用,不用于临床诊断 ## 一句话结论 异位组织可存在于前胃的固有层(主要)、黏膜下层或浆膜下层。异位组织可为任何类型,但胰腺(Figure 1、Figure 2)、肝脏(Figure 3、Figure 4)和肠(Figure 5)常见。 ## 病变描述(中文) 异位组织可存在于前胃的固有层(主要)、黏膜下层或浆膜下层。异位组织可为任何类型,但胰腺(Figure 1、Figure 2)、肝脏(Figure 3、Figure 4)和肠(Figure 5)常见。在某些情况下,它可与覆盖其上的鳞状上皮增生相关联。对于异位肠,肠道相关淋巴组织的存在不应被误认为炎症。异位组织被视为偶发性发现。 ## 诊断与分级建议(NTP 共识,中文) 无论何时出现,异位组织都应被诊断,但不进行分级。诊断应随其来源组织加以修饰。 ## 英文原文 · Comment Ectopic tissue can be present in the lamina propria (primarily), submucosa, or subserosa of the forestomach. Ectopic tissue can be of any type, but pancreas ( Figure 1 and Figure 2 ), liver ( Figure 3 and Figure 4 ), and intestine ( Figure 5 ) are common. In some cases, it can be associated with hyperplasia of the overlying squamous epithelium. With ectopic intestine, the presence of gut-associated lymphoid tissue should not be mistaken for inflammation. Ectopic tissue is considered an incidental finding. ## 英文原文 · Recommendation Whenever present, ectopic tissue should be diagnosed but not graded. The diagnosis should be modified with the tissue of origin. ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0077.jpg - https://www.labsmart.cn/ntp-atlas-images/ntp_0082.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
