Papilloma - Definition

Ask a question


A papilloma refers to a lesion located on the skin or a mucous membrane, the tissue lining the inside of certain organs. It constitutes a small benign tumor, generally projecting from the surface of the skin, produced by an abnormal increase in papilla size, small rough forms located on the skin or a mucous membrane. A papilloma can be idiopathic, that is to say without known cause, or secondary to specific causes, such as a virus (notably papillomavirus) or infection. The consequences of a papilloma are essentially in regards to appearance. Papillomas are commonly observed on the eyelid.
