An insight to pilonidal sinus etiology; interdigital pilonidal sinus

Abstract

A 46-year-old man who was working in leather tanning industry presented to our department with a mass and intermittent purulent discharge on his left hand for three years. Total excision was performed using transpositional flap. Histopathology was compatible with pilonidal sinus. Interdigital pilonidal sinus of the hand is a rare occupational disease. It is frequently encountered in hairdressers. Penetration of foreign hair to the interdigital web space is the cause of the disease.
