异位组织Ectopic Tissue · 甲状腺 · 内分泌系统 · NTP ntp-0061
诊断要点:甲状腺内的异位组织只要存在即应诊断,但该改变不需要严重程度分级。诊断应注明组织来源进行修饰(例如,甲状腺 - 异位组织,胸腺)。
病变描述
异位胸腺组织是一种先天性改变,胸腺外组织位于甲状腺邻近(Figure 1)或甲状腺内(Figure 2)。异位胸腺可同时具有皮质和髓质组织,以及哈索尔小体(Hassall's corpuscles)。异位胸腺是一种发育异常,偶尔可见于大鼠和小鼠,通常与处理无关,但胚胎期开始的暴露可能潜在影响胸腺异位的发生。
诊断与分级建议(NTP 共识)
甲状腺内的异位组织只要存在即应诊断,但该改变不需要严重程度分级。诊断应注明组织来源进行修饰(例如,甲状腺 - 异位组织,胸腺)。

Comment:
Ectopic thymic tissue is a congenital change with the extrathymic tissue located either adjacent to ( Figure 1 ) or within ( Figure 2 ) the thyroid gland. The ectopic thymus may have both cortical and medullary tissue, as well as Hassall’s corpuscles. Ectopic thymus is a developmental abnormality that can occasionally be found in rats and mice and is generally unrelated to treatment, but exposures beginning during embryogenesis may potentially affect the occurrence of thymic ectopia.
Recommendation:
Ectopic tissue in the thyroid gland should be diagnosed whenever present, but a severity grade is not needed for this change. The diagnosis should be modified with the tissue of origin (e.g., Thyroid gland - Ectopic tissue, thymus).
