Thyroglossal duct cyst represents a congenital anomaly of the cervical region, rarely documented in animals. Although previously reported in dogs, cats, horses, goats, pigs, and calves, never in birds. This report describes a rare case of thyroglossal duct cyst in a hen. A necropsy of a Transylvanian Naked Neck hen carried following diphtheroid mucocutaneous lesions. The necropsy revealed a large, cyst-like structure measuring 0.5 cm at the level of the caudal edge of the left thyroid gland. Histologically, the cystic mass, bordered by 1-2 lines of well-differentiated ciliated cuboidal cells, presented nuclear immunoreactivity for Thyroid transcription factor 1. To the best of the authors' knowledge, there are no previous records of thyroglossal duct cysts in avians. Moreover, this is the first case describing a thyroglossal duct cyst in a hen.
甲状舌管囊肿是一种颈部先天性异常，在动物中鲜有记录。虽然此前在犬、猫、马、山羊、猪和小牛中都有报道，但从未在鸟类中出现过。本报告描述了一例母鸡甲状舌管囊肿的罕见病例。对一只患有类白喉性黏膜皮肤病变的特兰西瓦尼亚裸颈母鸡进行了尸检。尸检发现，在左甲状腺尾缘水平处有一个大小为0.5厘米的大型囊肿样结构。组织学检查显示，该囊性肿物由1 - 2层分化良好的纤毛立方细胞构成边界，呈现甲状腺转录因子1的核免疫反应性。据作者所知，此前尚无禽类甲状舌管囊肿的记录。此外，这是首例描述母鸡甲状舌管囊肿的病例。
