Detection of Equus caballus papillomavirus-2 in equine penile/preputial papillomas and squamous cell carcinomas in southern Brazil.

ABSTRACT: For approximately one decade, a novel papillomavirus termed Equus caballus papillomavirus-2 (EcPV-2) has been associated with equine penile/preputial papillomas and squamous cell carcinomas (SCCs). It is currently believed that the virus has a carcinogenic activity, being able to induce such neoplastic lesions. After being first described, EcPV-2 has been detected in many countries from North America, Europe, and Asia; however, to date, it has not been reported in Brazil. The aim of this research was to investigate the presence of EcPV-2 in penile/preputial papillomas and SCCs of Brazilian horses. Forty samples diagnosed as equine penile and/or preputial papillomas, carcinomas in situ (CIS), or SCCs in two veterinary anatomic pathology services from southern Brazil were investigated. Histo
