Noureddine Njoumi*, Hicham Laraqui, Mohamed Najih, Aziz Zentar and Abdelmounaim Ait Ali
The pilonidal sinus or cyst in the perianal area is a rare presentation of a common pathology. Pilonidal sinus is usually arising in the region of natal cleft, only less than 20 cases have been reported in the perianal area. This unusual localization of pilonidal sinus may pose a differential diagnosis challenge mainly with anal fistula and hidradenitis suppurativa. It may also have specific therapeutic implications linked to localization. We report a case of perianal pilonidal sinus in a 23-year-old young man who was admitted for treatment of anal fistula, it was only intraoperatively that the pilonidal sinus was diagnosed. Some technical devices are provided to remove the diagnostic doubt and apply the appropriate treatment. The surgical excision was performed and the patient has a good recovery.
