[Interdigital pilonidal sinus ("barber's disease")--a rare occupational disease].

Barber's disease is produced by short hairs that penetrate the interdigital spaces of the hands. The following chronic inflammatory reaction causes fistulas or sinuses and cysts. We present the case of a patient with interdigital pilonidal sinuses of all web spaces in both hands. Such an extensive case of this occupational disease has so far not been reported.
