Extensive Definition

Papilloma refers to a benign epithelial tumor growing exophytically (outwardly projecting) in finger-like fronds. In this context Papilla refers to the projection created by the tumor, not a tumor on an already existing papilla (such as the nipple.)
When used without context, it frequently refers to infections caused by Human papillomavirus. However, there are other conditions that cause papilloma, such as Choroid plexus papilloma (CPP).
Two types of papilloma often associated with HPV are "squamous cell papilloma" and "transitional cell papilloma" (also known as "bladder papilloma".)
