What is a pilonidal cyst?

A pilonidal cyst is a small sac inside the skin that is usually located near the tailbone at the top of the buttocks crease. Pilonidal (say: “pie-low-NYE-dull”) means “nest of hairs.” A pilonidal cyst can contain hair, skin fragments and other abnormal tissue.

Anyone can have a pilonidal cyst, but it is more common in young men.
