Papillomas in black and white colobus monkeys (Colobus polykomus)

Area of Science:

• Veterinary Pathology
• Primate Dermatology
• Neoplastic Disease Research

Background:

• Colobus polykomus (black-and-white colobus) are Old World monkeys native to Africa.
• Papillomas are benign epithelial tumors caused by papillomaviruses.
• Understanding viral-induced neoplasms in non-human primates is crucial for comparative pathology.

Observation:

• Two Colobus monkeys were found to have multiple papillomatous growths.
• The growths exhibited a cauliflower-like morphology.
• Lesions were distributed across the palmar and plantar surfaces, as well as digits of all four limbs.

Findings:

• Papillomas ranged in size from 10 to 25 mm.
• The affected areas included palms, soles, fingers, and toes.
• The consistent location suggests a potential tropism for these specific epidermal sites.

Implications:

• This case report contributes to the limited literature on papillomavirus infections in Colobus monkeys.
• Further research may elucidate the specific papillomavirus strain involved and its pathogenesis.
• Findings may inform veterinary care and conservation strategies for Colobus populations.
