A conjunctival papilloma is a benign epithelial growth on either the bulbar or tarsal conjunctiva. When due to viral causes, they are called verrucae. Very rarely can these lesions become malignant. There is a strong association between human papilloma virus (HPV) types 6 and 11 and conjunctival papillomas. The classification of these lesions can be based on cause or gross appearance. Thus, these lesions can be infectious, viral, squamous cell (infectious viral etiology), limbal, and inverted. Furthermore, they can be pedunculated (synonymous with infectious and squamous cell type) or sessile. Limbal lesions (which are sessile) are noninfectious and are believed to arise from UV radiation. Squamous cell papillomas are seen mostly in those less than 20 years of age, while limbal papillomas are seen more often in older adults. Depending on the size and location, these lesions can be irritating, cause tearing or blurring of vision, or simply be cosmetically unappealing.
