What is pilonidal disease?
Also known as: pilonidal cyst, pilonidal sinus, PNS.
Pilonidal disease is one or more skin openings between the top of the cheeks of the buttocks. A pilonidal sinus is a small tunnel in the skin which may fill with fluid. It is also known as a pilonidal cyst when containing hair, dirt and skin debris or a pilonidal abscess when infected with bloody secretions. It’s more common in adult men, though it can occur particularly in hairy adolescents.
