Facts about Wildlife Diseases: Warts in White-tailed deer (Cutaneous Fibromas).

Abstract

Deer warts, or cutaneous fibromas, are skin tumors caused by papillomavirus infection that affect white-tailed deer and other deer. These growths are generally benign, but in rare cases may proliferate and impede functions like sight, movement, or feeding. Deer immune systems usually eradicate the infection over time. Found exclusively on the skin, usually around the eyes, neck, face, and forelegs, warts may be diverse in appearance and size, ranging from small fleshy nodules to larger, pendulous masses or clusters. Transmission mechanisms are suspected to involve skin contact or possibly insect vectors but remain unclear. Diagnosis is by visual examination and histopathological analysis of the wart tissue. Wild deer populations usually do not require treatment, but surgical removal is an option for captive herds. Vaccine development remains plausible but has not yet been pursued extensively.
