Malignant neoplasms occur commonly in cattle, with lymphosarcoma being the most common. Chondrosarcoma rarely has been described and only in mature cattle. The present report describes a chondrosarcoma of the left scapula of an 8-month-old Holstein steer. Histologic examination of the mass revealed an unencapsulated, multilobular neoplasm composed of neoplastic spindle cells embedded in irregular islands of chondroid matrix, consistent with a diagnosis of chondrosarcoma.
恶性肿瘤在牛中很常见，其中淋巴肉瘤最为常见。软骨肉瘤很少被描述，且仅见于成年牛。本报告描述了一头8个月大的荷斯坦公牛左肩胛骨的软骨肉瘤。对该肿块进行组织学检查发现，它是一个无包膜的多叶肿瘤，由嵌入不规则软骨样基质岛中的肿瘤性梭形细胞组成，符合软骨肉瘤的诊断。
