A mass involving the maxilla of a cow was determined to be an osteosarcoma. Microscopically, the mass was composed of plump pyriform cells aligned along thin trabeculae of osteoid. Osteosarcoma rarely develops in large animal species, but when it does, it is usually found in the skull and must be differentiated from more common diseases, such as actinomycosis and tooth abscesses.
一头奶牛上颌骨的肿物被确诊为骨肉瘤。显微镜下，该肿物由沿纤细类骨质小梁排列的饱满梨形细胞组成。骨肉瘤在大型动物物种中很少发生，但一旦发生，通常见于颅骨，并且必须与放线菌病和牙齿脓肿等更常见的疾病相鉴别。
