Pilonidal sinus. Close-up of a pilonidal cyst in the cleft between the buttocks of a 22-year-old male patient. A pilonidal sinus is a cyst or abscess near or on the natal cleft of the buttocks that often contains hair and skin debris. One proposed cause of pilonidal cysts is ingrown hair. Excessive sitting is thought to predispose people to the condition because they increase pressure on the coccyx region | |
