Abstract

An interdigital pilonidal sinus is considered a rare occupational disease related to individuals with short hair. We describe a case of a 44-year-old man who presented with a tender nodule with a purulent discharge in the fourth interdigital web space of the left foot. The biopsy specimen showed a sinus tract surrounded by keratin and squamous epithelium, and the track contained acute and chronic inflammatory cells. The skin lesion was improved with occlusion of the fistula by using 100% bichloracetic acid. We herein report on a rare case of a interdigital pilonidal sinus in the foot, and this occurred with no relation to the patietn's occupation.
