Nasal chondrosarcoma in a Simmental cow.
The pathologic features of a nasal chondrosarcoma, a rare tumor of bovines, in a Simmental cow are described. Upon clinical examination, stertor, difficulty in breathing, poor body condition, and a nasal mass were found. Histopathologic examination revealed that the mass was composed mostly of numerous cartilaginous lobules surrounded by spindle-shaped cells, often showing mitotic figures, atypical chondrocytes, and lacunae containing 2 or more cells. On the basis of the histological features, the mass was diagnosed as a nasal chondrosarcoma.
