Pilonidal (say py-luh-NY-dul) disease is a chronic skin infection in the crease between the buttocks. People with this condition have one or more cysts in that area that tend to get inflamed and infected. A pilonidal cyst may look like a small dimple (called a pit or  sinus ).Hair may stick out from it.xperts think pilonidal cysts may form in one of three ways: 1  A hair follicle in the skin becomes irritated or stretched. 2  A loose hair may get trapped in the crease between the buttocks. 3  Some cysts may be present at birth (congenital).
