Summary
Corneal dermoid, a rare condition in beagles, involves hair growth on the eye
Area of Science:
- Veterinary Ophthalmology
- Canine Pathology
Background:
- Corneal dermoid is a congenital condition characterized by the presence of choristomatous tissue on the cornea.
- While documented in various dog breeds, its occurrence in laboratory beagle dogs is considered rare.
Purpose of the Study:
- To report and characterize two cases of corneal dermoid in young male laboratory beagle dogs.
- To document the gross and histopathological findings associated with this condition in this specific canine population.
Main Methods:
- Gross examination of the affected corneas in two beagle dogs.
- Histopathological analysis of the corneal tissue to identify its components.
- Inquiry with breeders regarding the incidence of corneal dermoid in laboratory beagles.
Main Results:
- Two male laboratory beagles presented with corneal dermoid, exhibiting hair growth from the cornea.
- Histopathology confirmed the presence of epidermal and dermal appendages, including hair follicles, sebaceous glands, and adipose tissue within the corneal stroma and epithelium.
- Regrowth of hair was observed approximately 70 days after removal in one case.
Conclusions:
- Corneal dermoid, though rare, can occur in laboratory beagle dogs.
- The condition involves the presence of skin-like appendages on the cornea, requiring detailed histopathological confirmation.
- Further investigation may be warranted to understand the specific predisposing factors in this breed, if any.
