异位组织Ectopic Tissue · 肾脏 · 泌尿系统 · NTP ntp-0153
诊断要点:异位组织存在时应予以诊断,但不应进行分级。诊断应注明组织来源加以修饰(例如,肾脏 - 异位组织,肝)。
病变描述
在罕见情况下,肾脏中可见各种肾外组织灶,尤其是靠近被膜处。已有报道发现肝组织和肾上腺组织(Figure 1、Figure 2)。这些异位组织为自发性发生,无病理学或毒理学意义。必须将其与原发或转移性肿瘤的存在相鉴别。

Comment:
In rare cases, various foci of extrarenal tissue can be noted in the kidney, particularly near the capsule. Liver tissue and adrenal tissue have been reported ( Figure 1 and Figure 2 ). These ectopic tissues occur spontaneously with no pathologic or toxicologic significance. They must be differentiated from the presence of either primary or metastatic neoplasia.
Recommendation:
Ectopic tissues should be diagnosed when present but should not be graded. The diagnosis should be modified with the tissue of origin (e.g., Kidney - Ectopic tissue, Liver). Related Links: Kidney - Metaplasia, Osseous
