Nose Cancer (Chondrosarcoma) in Dogs Chondrosarcoma of the Nasal and Paranasal Sinuses in Dogs A chondrosarcoma (CSA) is the second most common primary tumor in dogs, accounting for ten percent of all primary bone tumors. This is a malignant, invasive and fast spreading tumor in dogs. A CSA of the nasal and paranasal sinuses arises from the mesenchymal tissue, a connective collagenous tissue that is found throughout the body, and metastasizes to other parts of the body, including the nasal bones. It usually occurs on one side of the nasal cavity and extends to the other side over time. Breeds that have been reported to be predisposed to nasal tumors are German short-haired pointers, German shepherds, keeshonds, basset hounds, collies, old English sheepdogs, Shetland sheepdogs, and Airedale terriers. Dolichocephalic breeds are at higher risk than brachycephalic dogs, males are more predisposed than females, and older dogs are more likely to be affected. In addition, it is believed that animals in urban areas may be more at risk for developing nasal tumors than animals in rural areas. The average age reported is seven years and older.
