Feline Squamous Cell Carcinoma: Role of Papillomavirus
November 2nd, 2009 Posted in papillomavirus, squamous cell carcinoma
Squamous cell carcinomas (SCC) are among the most common malignant skin cancers of cats. There is evidence that papillomaviruses promote SCC development on sun-exposed areas in humans. About 100 papillomaviruses are known in humans, but only a few in dogs and cats. Previous reports have identified papillomaviruses in a certain proportion of canine SCC. This paper describes the identification (using PCR) of viral DNA from two distinct papillomaviruses in an invasive SCC on the nose of a 15-year-old cat. One of the two viruses has never been described before. It is also the first time that multiple papillomaviruses have been detected in a single cancerous lesion in a cat. This finding supports the association between papillomaviruses and SCC in cats. If papillomaviruses influence the development of feline SCC, new approaches to treatment may be possible. [MK]
