Summary
A seminoma, a type of testicular tumor, was identified in an adult male owl monkey. This finding contributes to understanding reproductive health and pathology in non-human primates.
Area of Science:
- Veterinary Pathology
- Primate Reproductive Biology
- Comparative Oncology
Background:
- The case involves an adult male Aotus nancymae (Nancy Ma's night monkey) utilized for breeding.
- The animal was presented for surgical intervention due to an abnormality in the left testicle.
Observation:
- Surgical removal of the left testicle revealed a mass approximately two to three times the normal size.
- The mass exhibited a soft, white to pale gray appearance on cut surface and protruded beyond surrounding tissue.
Findings:
- Microscopic examination of the excised tissue confirmed the presence of a tumor.
- The morphology of the neoplastic cells was characteristic of a seminoma.
Implications:
- This case report adds to the limited literature on testicular neoplasms in Aotus nancymae.
- Understanding spontaneous tumors in primates aids in comparative oncology and veterinary diagnostics.
- Highlights the importance of reproductive health monitoring in captive breeding programs for non-human primates.
