Abstract

Feline Bowenoid in situ carcinoma (BISC) is a rare disease that presents as multiple discrete plaques of epidermal hyperplasia and dysplasia. Two studies using immunohistochemistry revealed papillomaviral antigens in 11% and 47% of BISCs. Additionally, a recent study detected papillomaviral DNA in 24% of BISC lesions. To further investigate the association between papillomaviruses and BISC, polymerase chain reaction using consensus primers was used to detect papillomaviral DNA in 18 formalin-fixed samples of BISC. Papillomaviral DNA was amplified from 11 of the samples but from none of the controls. Six amplicons were sequenced; one was homologous with a papillomavirus from a human patient with multiple cutaneous squamous cell carcinomas and the other five showed weak homology to human papillomavirus type 17. These five sequences were > 96% homologous over a 235 bp sequence, indicating the presence in all five BISCs of one papillomavirus type distinct from any previously sequenced and more closely related to human than animal papillomaviruses. The results confirm an association between BISC and papillomaviruses, and as all six papillomavirus sequences identified are closely related to human papillomaviruses, it is possible that the virus is transmitted from humans to cats or vice versa.
