A pilonidal cyst occurs at the bottom of the tailbone (coccyx) and can become infected and filled with pus. Once infected, the technical term is pilonidal abscess. Pilonidal abscesses look like a large pimple at the bottom of the tailbone, just above the crack of the buttocks. It is more common in men than in women. It usually happens in young people up into the fourth decade of life.

People thought the cysts were due to irritation from riding in bumpy Jeeps. For a while, the condition was actually called "Jeep disease."
