Extragonadal teratoma in the head and neck region is unusual in veterinary medicine. So far, only one case of oropharyngeal teratoma has been reported in a cat.
In this report, a 5-month-old kitten was brought to the clinic with the complaint of difficulty breathing, food intake, and oropharyngeal mass. In clinical examination, there was a large mass, protruding from the localization included left buccal mucosa, soft palate, and extending into the oropharynx but no cranial extension was observed in CT scans. The mass was completely resected. Macroscopically, the mass measured 4.5 × 6.5 cm and contained solid and cystic areas associated with soft and hard tissue components.
FINDINGS/TREATMENT AND OUTCOME: Histopathology revealed an extragonadal solid-cystic (grade 0) oropharyngeal mature teratoma containing structures from endoderm, mesoderm, and ectoderm. After an 8-month follow-up control period, no signs of recurrence were observed.
The case was deemed worthy of being presented with its clinical, radiological, and pathological findings, and complete resection was curative for mature teratoma.
头颈部性腺外畸胎瘤在兽医学中较为罕见。迄今为止，仅报道过1例猫口咽畸胎瘤。
在本报告中，一只5月龄小猫因呼吸困难、进食困难及口咽部肿物被带到诊所。临床检查发现一个大肿物，从包括左颊黏膜、软腭的部位突出，并延伸至口咽，但CT扫描未发现向颅部扩展。肿物被完整切除。大体上，肿物大小为4.5×6.5 cm，包含与软组织和硬组织成分相关的实性和囊性区域。
检查结果/治疗及转归：组织病理学显示为性腺外实性-囊性（0级）口咽成熟畸胎瘤，包含来自内胚层、中胚层和外胚层的结构。经过8个月的随访观察期，未观察到复发迹象。
该病例因其临床、放射学和病理学表现而值得报告，完整切除对成熟畸胎瘤具有治愈效果。
