Camelidae and Cervidae Papillomatosis – NAVLE Study Guide

Overview and Clinical Importance

Papillomatosis refers to viral-induced proliferative skin lesions caused by members of the Papillomaviridae family. In camelids and cervids, these lesions manifest primarily as fibropapillomas (also called cutaneous fibromas or "warts"), characterized by both epithelial and dermal proliferation. Understanding papillomatosis in these species is clinically important for accurate diagnosis, appropriate client communication, and differentiation from other cutaneous masses.

This condition represents an important topic for the NAVLE, particularly regarding species-specific presentations, diagnostic approaches, and treatment considerations in exotic and wildlife species.

Etiology and Pathogenesis

Causative Agents

Papillomaviruses (PVs) are small, nonenveloped DNA viruses with icosahedral capsids approximately 50-60 nm in diameter. They have a circular double-stranded DNA genome of 6,800-8,400 base pairs. The virus replicates exclusively in epithelial cells of skin and mucosal surfaces.
