Definition

A rare, benign (not cancer) tumor that forms in a hair follicle (the opening on the skin through which hair grows). Fibrofolliculomas appear as small, raised, whitish bumps that usually occur on the face, ears, neck, and chest. They tend to grow slowly but can increase in size and number over time. Fibrofolliculomas often occur in patients with an inherited condition called Birt-Hogg-Dubé syndrome.
