Equus caballus papillomavirus 8 (EcPV8) associated with multiple viral plaques, viral papillomas, and squamous cell carcinoma in a horse.
Abstract: Equus caballus papillomavirus 8, a recently discovered virus, has been reported to cause generalised papillomavirus in horses. Objective: To describe a case in which multiple viral plaques, viral papillomas, squamous cell carcinoma (SCC) in situ and invasive squamous cell carcinoma (ISCC) were associated with EcPV8 in a horse. Methods: Case report. Methods: A 16-year-old mixed breed horse presented with dozens of raised crusted papular to nodular lesions over a course of 4 years. Masses had been surgically excised four times and cisplatin beads and emulsion were implanted on three different occasions; however new masses continue to develop in sites of previous masses as well as new sites. Results: Multiple viral plaques, viral papillomas, SCC in situ and ISCC, localised to the inguinal region, were diagnosed via histopathology. EcPV8 DNA was detected via PCR. Conclusions: Since only a few cases have been reported, we do not know the incidence of EcPV8 nor how often it may be associated with SCC in situ or ISCC without further study. Conclusions: This is the fourth reported case of viral papillomatosis in the context of an EcPV8 infection in a horse. This is the first case in which SCC has been associated with EcPV8.

The paper describes a unique case of infection by the Equus caballus papillomavirus 8 (EcPV8) in a horse, which resulted in multiple viral plaques, papillomas, and squamous cell carcinoma (SCC) – a type of skin cancer.
Objective of the Study
The research aimed to document a peculiar case of a horse showing multiple symptoms associated with an infection of the recently identified Equus caballus papillomavirus 8 (EcPV8).
- This includes multiple viral plaques and papillomas, in addition to squamous cell carcinoma.
Research Methodology
This research consisted of a detailed study of a clinical case.
- A 16-year-old mixed breed horse with numerous elevated lesions over a period of four years was examined.
- The horse had undergone surgical removal of the masses four times, and had been treated with cisplatin beads and emulsion in three separate instances.
- Despite these measures, new masses continued to develop in previously affected and new areas.
Research Findings
Post investigation, the researchers found a few significant findings.
- Multiple viral plaques, papillomas, in addition to SCC and invasive squamous cell carcinoma (ISCC) were diagnosed.
- The afflictions were localized to the horse’s inguinal (groin) region.
- The detected disease-causing agent was EcPV8, identified through PCR testing.
Research Conclusions
The study ends with very important conclusions.
- Given only a few cases have been studied, it remains unclear how frequent EcPV8 occurrences are, or how often it may cause SCC or ISCC.
- This was the fourth reported case of viral papillomatosis associated with an EcPV8 infection in a horse.
- Importantly, this is the first reported instance where SCC has been associated with an EcPV8 infection.
