Summary
A subcutaneous fibroma, a benign skin tumor, was diagnosed in a pitbull dog with eyelid swelling. Surgical removal resulted in no recurrence, suggesting fibromas are treatable eyelid masses.
Area of Science:
- Veterinary Medicine
- Ophthalmology
- Dermatology
Background:
- Eyelid masses in dogs can present with various clinical signs, including swelling.
- Subconjunctival swelling requires thorough diagnostic evaluation to determine the underlying cause.
Observation:
- A 9-year-old castrated male pitbull presented with a 10-day history of subconjunctival swelling.
- Ophthalmic examination revealed a subcutaneous mass at the right lateral canthus.
Findings:
- Excisional biopsy and histopathological analysis confirmed the mass as a subcutaneous fibroma.
- The dog showed no evidence of recurrence 11 months post-surgery.
Implications:
- Subcutaneous fibroma should be considered in the differential diagnosis for rapidly enlarging eyelid masses in dogs.
- Surgical excision appears to be an effective treatment for canine subcutaneous fibromas with a good prognosis.
