Abstract

A 14-year-old, neutered male domestic shorthair cat presented for acute monoparesis with physical exam findings and biochemical data supportive of a distal arterial thromboembolism. Thoracic radiographs revealed an alveolar pattern in the right middle lung lobe and multifocal nodules in other lung lobes. A pulmonary mass was found on necropsy, which was composed of both carcinomatous and sarcomatous components, confirmed with cytokeratin and vimentin immunohistochemistry. Using the World Health Organization classification scheme for mixed pulmonary tumors, this tumor would be characterized as a pleomorphic squamous cell carcinoma under the umbrella term of pulmonary sarcomatoid carcinoma. The World Health Organization classification of mixed pulmonary tumors and its application to previously reported mixed pulmonary tumors in companion animals is discussed. This is the first reported case of this tumor type in a cat, as well as the first report of this tumor type associated with an arterial thromboembolism in any veterinary species.

猫肺肉瘤样癌伴动脉血栓栓塞。

一只14岁，绝育的雄性家养短毛猫因急性单眼而就诊，体检结果和生化数据支持远端动脉血栓栓塞。胸片示右肺中叶肺泡型，其他肺叶多灶性结节。尸检发现肺肿块，由癌性和肉瘤性成分组成，细胞角蛋白和波形蛋白免疫组化证实。根据世界卫生组织对混合性肺肿瘤的分类方案，该肿瘤的特征为肺肉瘤样癌总称下的多形性鳞状细胞癌。本文讨论了世界卫生组织对混合性肺肿瘤的分类及其在伴侣动物混合性肺肿瘤中的应用。这是在猫中首次报道的这种肿瘤类型病例，也是在任何兽医物种中首次报道的与动脉血栓栓塞相关的这种肿瘤类型。
