Material and methods. The study has covered 32 randomly selected patients aged 20 to 40 years with pilonidal sinus after surgical treatment carried out in the Department of General and Vascular Surgery, Provincial Specialist Hospital Nicholas Pirogow in Lodz and Department of Oncological Surgery Hospital of the Ministry of Internal Affairs with Warmia and Mazury Oncology Center in Olsztyn in the years 2007-2013.

We analyzed the results of histopathological preparations cyst cut the hair. Based on medical records analyzed the duration of inflammation of the onset of symptoms the patient until surgery.
Results. In the group of 32 patients, inflammation in the natal cleft lasted from 3 months to 25 months (mean 8.28 months). There were no neoplasm cells in a histopatological examination after surgery. None of the patients had no recurrence.
Conclusions. In the analyzed group of patients after pilonidal sinus surgery, histopathology examination did not show malignant transformation. As one of the causes of the results must take into account the short period between the onset of symptoms of inflammation and surgery. These observations require confirmation in a larger group of patients.
