Summary
A uterine leiomyoma, a common reproductive tumor in primates, was identified in a squirrel monkey (Saimiri sciureus). This case marks the first reported instance of this specific tumor in this species.
Area of Science:
- Veterinary Medicine
- Primate Oncology
- Reproductive Pathology
Background:
- Uterine leiomyomas are common in nonhuman primates.
- Squirrel monkeys (Saimiri sciureus) are a common species in research.
Observation:
- A 3.0 x 2.5 cm abdominal mass was detected in an adult female squirrel monkey.
- Radiography and ultrasonography were inconclusive in identifying the mass's origin.
- Exploratory laparotomy revealed the mass within the uterus.
Findings:
- Gross examination showed a solitary, firm, unencapsulated tumor.
- Histologic analysis revealed interlacing smooth muscle bundles consistent with leiomyoma.
- The tumor exhibited low mitotic activity.
Implications:
- This is the first documented case of a uterine leiomyoma in a squirrel monkey.
- This finding contributes to the understanding of reproductive tumors in this primate species.
- Further research may explore the incidence and characteristics of uterine leiomyomas in squirrel monkeys.
