A pilonidal sinus is a small hole, tunnel or pit of the skin. It is usually located in the fold between the buttocks but can develop elsewhere, including the hands and feet (interdigital spaces). It generally contains embedded hair and can become infected, resulting in abscess formation with pain and discharge. It is most common in young adult males.
The diagnosis is made on clinical grounds, from the history and findings on examination. The diagnosis can be made by a treating GP.
The relevant medical specialist is a general surgeon.
