Pilonidal disease of the umbilicus--a report of two cases

Two cases of umbilical pilonidal sinus are reported herein. Both patients were young adult males aged 21 and 27 years, respectively. The predisposing factors are briefly discussed, however, the exact etiology of this disease remains unknown. Umbilectomy is the most commonly offered treatment and although it is rare, this entity probably goes undiagnosed in the majority of cases.
