Pilar cysts are commonly found on the scalp, may interfere with hats or helmets, and are usually removed when symptomatic.

This large pilar cyst exerted pressure against the skin and has destroyed follicles.

Roughly 90% of cysts appear on the scalp, with the remaining 10% on the face, neck, back, and scrotum. Removal of scrotal pilar cysts can be accomplished by incision, similar to ones on scalp.
