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. ## 英文原文 · 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). ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0291.jpg - https://www.labsmart.cn/ntp-atlas-images/ntp_0293.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
