Rare Location for Pilonidal Sinus: the Nasal Dorsum

Pilonidal sinuses are recurrent chronic inflammatory lesions which may occur due to penetration of hair particles into skin. Herein, the authors report a pilonidal sinus case that is unusually seen on nasal dorsum and totally excised with the open technique rhinoplasty method. A 20-year-old male patient was admitted to the authors' outpatient clinic with complaints of dysmorphism and discharge from nasal dorsum. Physical examination revealed a swelling in nasal dorsum and hair-containing fistula. Excision was performed with an open rhinoplasty approach. Histo-pathology examination revealed pilonidal sinus. While pilonidal sinus is usually located in sacro-coccygeal region, it may also be seen in atypical localizations like nasal dorsum. Although the prediagnosis of a hair-containing lesion usually includes dermoid cyst, pilonidal sinus should also be considered and histo-pathological examination should certainly be performed. It is a problematic condition when it is symptomatic; however, management and treatment of the disease is easy when correct diagnosis is made.
