Abstract Pilonidal sinus is a term first used by Hodges in 1880 to describe granulomatous lesions containing hairs in its interior. The presence of endoanal pilonidal sinus is rare and only nine cases have been reported in medical literature. This article describes a male, 42 years, initially submitted to fistulotomy with seton placement that four years later evolved with complaints of anal purulent discharge associated with painful anal groin. During the first evaluation a small endoanal tumor was found. It was located in posterolateral anus position and contained hair in its interior, without purulent discharge at that moment. Underwent surgery that confirmed the presence of endoanal pilonidal sinus. The sinus was opened and left to heal by secondary intention. The patient had good outcome with no signs of recurrence.
