While investigating the intrinsic vasculature of the canine thyroid gland, atypical thyroid follicles were observed histologically, arising from a postnatal thyroid cyst of unknown origin, in stained sections of a male, 1-year-old, mesaticephalic dog. The animal was anesthetized, bled, killed by injection of Toxital directly into the heart, and perfused with 10% buffered neutral formalin solution. The thyroid tissue was fixed, embedded in paraffin, sectioned serially, and mounted on glass slides. Concordant with descriptions in the literature, this structure appeared to be a postnatal ultimobranchial-like cyst with direct connections to both ultimobranchial and mixed follicles. Seemingly, this observation has never been reported previously in the canine and would lend support to the hypothesis that ultimobranchial-like cysts may give rise to these atypical follicles. However, the authors are not totally convinced that all such thyroid cysts are solely ultimobranchial in orgin. A review of the literature supporting this contention is discussed.
在研究犬甲状腺的固有血管系统时，在一只1岁、中脑型雄性犬的染色切片中，组织学观察到非典型甲状腺滤泡，其源自一个不明来源的产后甲状腺囊肿。该动物经麻醉、放血后，通过直接向心脏注射托昔尔（Toxital）处死，并用10%缓冲中性福尔马林溶液灌注。甲状腺组织固定、石蜡包埋、连续切片并 mounted 在载玻片上。与文献描述一致，该结构似乎是一个产后鳃后体样囊肿，与鳃后体和混合滤泡均有直接连接。显然，这一观察结果此前在犬类中从未有过报道，这将支持鳃后体样囊肿可能产生这些非典型滤泡的假说。然而，作者并不完全确信所有此类甲状腺囊肿的起源都仅为鳃后体。本文讨论了支持这一观点的文献综述。 （注：原文中“mounted on glass slides”这里的“mounted”翻译为“裱贴、固定等意思较合适，这里意译为‘mounted 在载玻片上’以便更通顺理解，你可根据实际需求调整）
