a rare case of pilonidal sinus of the umbilicus

Abstract

Although most cases of pilonidal sinus are found in the sacrococcygeal region, umbilical presentations can occur as well. There are only a few reports of umbilical pilonidal sinus in the literature. We report a case of umbilical pilonidal sinus in a 26-year old man. Umbilectomy was carried out and the microscopic findings revealed umbilical pilonidal sinus. The present paper recapitulates the microscopic features and treatment of this rare disease.
