study of 4085 sacrococcygeal pilonidal sinus diseases’ pathological results in 12 years

Background: in some minimally invasive approaches, the cavity of the sacrococcygeal pilonidal cyst is not resected. this condition brings to mind the necessity of pathological examination of this cavity. in this study, we aimed to investigate whether or not the resected pilonidal cyst should be examined pathologically. methods: four thousand and eighty-five patients who had undergone resection of a pilonidal cyst were included in the study. preoperative findings and clinicopathological features were analyzed retrospectively. ibm spss statistics for windows version 25.0 was used for statistical analyses. quantitative variables were reported as median (minimum-maximum). results: the median age of the patients was 30 (2–87) years. 3,256 (79.7%) patients were male. one hundred and sixty-six (4%) patients were over 50 years. the median pathological specimen length was 5 (0.5–6.5) cm. the median time to pathological result was 6 (0–65) days. the most common diagnosis was a pilonidal sinus (n=3,917, 95.9%). no malignancy was detected after the histopathological examination. conclusion: in the absence of suspicious clinical findings, the histopathological evaluation of a resected pilonidal cyst is unnecessary due to the low malignancy rate.
