Histological analysis of pilonidal sinus specimens is generally unnecessary for patients under 50. However, routine histological review should be considered for older patients with chronic pilonidal disease.
Area of Science:
- General Surgery
- Pathology
- Oncology
Background:
- Pilonidal sinus is a common condition, primarily treated with surgery.
- Malignant degeneration is rare (0.1%), typically in patients over 50 with chronic disease.
Purpose of the Study:
- To evaluate the necessity of routine histological analysis of pilonidal sinus specimens.
Main Methods:
- A 10-year retrospective observational study of pilonidal sinus excisions.
- Analysis of 320 histological specimens from 325 resections.
Main Results:
- Pilonidal sinus confirmed in 312 specimens.
- Eight benign findings and zero malignancies were identified.
- No malignant degeneration was detected in the analyzed specimens.
Conclusions:
- Routine histological examination of pilonidal sinus specimens is not essential.
- Consider histological review for patients over 50 with chronic pilonidal disease.
