Squamous papillomas are benign neoplasms, which may affect the conjunctival & mucosal surfaces. Young dogs may be affected by significant numbers of viral papillomas, typically developing on the conjunctival and eyelid surfaces as well as the mucous membranes of the oral cavity. Adult animals more frequently display single discrete papillary eyelid lesions, which are pink to tan in color and often sessile with a “stalk-like” base.
