Summary
A horse with lameness was found to have a villonodular lesion in its leg. Surgical removal and treatment led to the horse
Area of Science:
- Equine surgery
- Veterinary pathology
- Equine sports medicine
Background:
- A 4-year-old Standardbred trotter presented with left forelimb lameness.
- Previous infectious arthritis in the left metacarpophalangeal joint suggested severe cartilage damage.
Observation:
- Arthroscopy revealed a large, presumed villonodular lesion.
- Surgical excision of the mass was performed.
Findings:
- Histopathology showed granulation tissue with keratinized epithelium.
- The lesion is hypothesized to be secondary to epithelial cell implantation into a reactive villonodular site.
Implications:
- This case highlights a potential cause of lameness in athletic horses.
- Understanding lesion etiology aids in diagnosis and treatment of similar conditions.
- Successful surgical management allowed the horse to return to racing.
