Report of a self-resolving corneal viral papilloma in a dog.

A 10-month-old male castrated beagle dog, without prior history of ocular disease, was referred for a corneal mass of the right eye. A non-painful raised mass with frond-like projections originated from the dorsotemporal paraxial cornea of the right eye. In addition, a plaque-like conjunctival lesion and several raised, smooth masses of the eyelid were noted around the right eye. An incisional biopsy of the corneal mass and an excisional biopsy of the conjunctival mass were performed. Histopathology confirmed the clinical diagnosis of viral papilloma. Conservative management with monitoring was elected, and the lesion self-resolved 3 mo after initial appearance. Key clinical message: This case suggests that monitoring is appropriate for corneal lesions definitively diagnosed as viral papillomas, as they may be self-limiting.
