Pilonidal sinus is a disease which is very common, especially in men and usually located in sacrococcygeal area. However, the disease can be also seen in rare localizations such as umblicus, forehead, scalp, clitoris, interdigital area and axilla. In the etiology of pilonidal sinus, acquired theory is accepted by most of surgeons instead of the congenital one. ⋯ In our opinion; surgical therapy of axillary pilonidal sinus, allows to complete resection in addition to absolute histopathological diagnoses and it may be an appropriate choice of treatment especially for the disease having one or two sinuses.
