Pilonidal sinus or sacrococcygeal fistula is a cyst or abscess near or on the natal cleft of the buttocks that often contains hair and skin debris. The sinus track goes in a vertical direction between the buttocks. Rarely, a pilonidal sinus occurs in other sites of the body.

The patient was admitted with a primary diagnosis of anal fistula at 5 o'clock in the “lithotomy position” and 2 cm from anal verge combined with cyst at 3 cm of the anal fistula. In anal inspection and rectal examination, the external orifice of the fistula with a 20 -30 mm induration and pus-like discharge were observed.
