INTERDIGITAL PILONIDAL SINUS
By Gary M. White, MD
Interdigital pilonidal sinus is an occupational disease of hairdressers in which a painful papule or nodule develops in the finger webs. A sinus through which hairs may be seen is characteristic.
- The third web space of the hands is most commonly affected.
- The hair is the customers (not the patient's) and is consistently thick, stiff and straight.
- A similar condition of the breasts may be seen in hair dressers [J Surg Case Rep. 2014 Jun; 2014(6)]
Excision may be done, although each hair usually works its way out over time.
