Pilonidal sinus caused by cutting trauma.
The implantation of hair in the deep corium is responsible for the production of pilonidal sinus. The mechanism responsible may be the drilling of hair, suction, implantation, or sequestration. Cutting trauma can be responsible for the production of pilonidal sinus, if the hair fragments are implanted in the deep corium of the skin.
