We studied 34 chondrosarcomas and 17 osteosarcomas among 285 sinonasal neoplasms in the dog. Mesenchymal chondrosarcomas (24) were more common than ordinary chondrosarcomas. Ultrastructural studies done in one case confirmed mesenchymal chondrosarcoma. Of the osteosarcomas, fibroblastic osteosarcoma (7) was the most common. In contrast to non-sinonasal skeletal neoplasms which are composed mostly (80%) of osteosarcomas, chondrosarcomas (66%) and mesenchymal chondrosarcomas (47%) were predominant among the sinonasal skeletal neoplasms of this study. The average age (ten years) of the dogs with sinonasal osteosarcoma was higher than that of dogs with non-sinonasal skeletal osteosarcoma, and there was a distinct male predominance in the dogs with osteosarcoma and chondrosarcoma. Large breed dogs and boxers, frequently affected with skeletal neoplasms, were not affected commonly with sinonasal osteosarcoma. The frequency of metastasis in the dogs with chondrosarcoma and osteosarcoma was much lower than that seen in dogs with nonsinonasal skeletal neoplasms.
我们在285例犬鼻窦肿瘤中研究了34例软骨肉瘤和17例骨肉瘤。间叶性软骨肉瘤（24例）比普通软骨肉瘤更常见。对1例进行的超微结构研究证实为间叶性软骨肉瘤。在骨肉瘤中，纤维母细胞性骨肉瘤（7例）最为常见。与非鼻窦骨骼肿瘤主要由骨肉瘤（80%）组成不同，在本研究的鼻窦骨骼肿瘤中，软骨肉瘤（66%）和间叶性软骨肉瘤（47%）占主导地位。患鼻窦骨肉瘤的犬的平均年龄（10岁）高于患非鼻窦骨骼骨肉瘤的犬，并且患骨肉瘤和软骨肉瘤的犬明显以雄性居多。经常患骨骼肿瘤的大型犬和拳师犬并不常患鼻窦骨肉瘤。患软骨肉瘤和骨肉瘤的犬的转移频率远低于患非鼻窦骨骼肿瘤的犬。
