Pilonidal sinuses are usually encountered in the sacrococcygeal region where they develop over a nidus of ingrown hair. Most cases present with abscess or cyst formation with intermittent discharge or cellulitis. Development of carcinoma in a Pilonidal sinus is a rare complication and is often seen in long standing untreated cases in advanced age. Here we present one such rare case encountered and discuss the possible underlying etiological factors, treatment and prevention strategies.

Keywords – squamous cell carcinoma, pilonidal sinus, chronic sinus disease.
