Abstract

Summary: Papillomaviruses (PVs) are small, non-enveloped DNA viruses that cause mucocutaneous tumours including squamous cell carcinoma (SCC) in man. In animals, evidence supports a causal role for PVs in the development of cutaneous and oral SCC in some species. In reptiles, three cases of papilloma or fibropapilloma have been associated with PV infection, but no association has been reported to date with SCC. Two cases of cutaneous epithelial tumours, multiple papillomas in a spiny-tailed lizard ( Uromastyx acanthinura ) and SCC in a Dumeril's boa ( Acrantophis dumerili ), were investigated by polymerase chain reaction. PV DNA was amplified from samples of both lesions. Typical microscopical features suggestive of PV infection (e.g. the presence of koilocytes) were observed in the lesions from the spiny-tailed lizard. This is the first report of an association between PV and SCC in reptiles. Further studies are needed to better clarify the role of PVs in these species and to characterize the PV strains involved.
