异位组织Ectopic Tissue · 前胃 · 消化系统 · NTP ntp-0209
诊断要点: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。
病变描述
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)
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。

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.
Recommendation:
Whenever present, ectopic tissue should be diagnosed but not graded. The diagnosis should be modified with the tissue of origin.
