Psoriasiform dermatosis in a rhesus monkey
The Journal of Investigative Dermatology
|February 1, 1981
Summary
A rhesus monkey developed a skin condition resembling human psoriasis vulgaris. This discovery offers insights into non-human primate dermatological research and potential comparative studies.
Area of Science:
- Veterinary Dermatology
- Primate Pathology
- Comparative Pathology
Background:
- Psoriasis vulgaris is a chronic inflammatory skin disease affecting humans.
- Understanding animal models is crucial for advancing dermatological research.
Observation:
- A rhesus monkey (Macaca mulatta) presented with chronic, scaling, erythematous plaques on the scalp, face, back, limbs, palms, and soles.
- Histopathological examination revealed epidermal changes such as acanthosis, parakeratosis, and reduced granular cell layer, alongside dermal changes including tortuous capillaries and inflammatory infiltrate.
Findings:
- The observed dermatosis in the rhesus monkey exhibited histopathological features consistent with human psoriasis vulgaris.
- Nutritional deficiency and systemic diseases were ruled out as causes for the monkey's skin condition.
Implications:
- This case highlights the potential of non-human primates as models for studying human skin diseases like psoriasis.
- Further research could explore the genetic and environmental factors contributing to psoriasis-like conditions in primates.
