[Causes of pilonidal sinus and pyoderma fistulans sinifica]
Abstract:
Pilonidal sinus is of the same origin as the Pyodermia fistulans sinifica . Both diseases are retention dermatopathies . These sinuses are not of congenital origin. Our observations have made an acquired origin seem more likely. Deep skin folds in the rima ani, the stiffness of the body hairs, the rolling movement of naturally separated hairs push the hair through the skin like a pin. If a hair is rubbed, it moves in the direction of its root with the peripherally directed hair scales. Excision of the sinus area and transplantation of an epithelial flap is the best therapy.
Insights
Pilonidal sinus and Pyodermia fistulans sinifica are acquired retention dermatopathies, not congenital. The best treatment involves surgical excision and epithelial flap transplantation.
Area of Science:
- Dermatology
- Surgical Pathology
Background:
- Pilonidal sinus and Pyodermia fistulans sinifica are classified as retention dermatopathies.
- The etiology of these conditions has been debated, with congenital origins previously suggested.
Observation:
- The study observed that pilonidal sinuses are not congenital.
- Acquired origins are strongly indicated by clinical observations.
- Deep anal folds, stiff body hairs, and hair movement contribute to the condition.
Findings:
- Pilonidal sinuses arise from acquired factors, specifically hairs penetrating the skin.
- Hair movement, driven by skin folds and friction, causes follicular penetration.
- This mechanism explains the 'pin-like' entry of hair into the dermis.
Implications:
- Understanding the acquired etiology reframes treatment strategies for pilonidal sinus.
- Surgical excision combined with epithelial flap transplantation is identified as the optimal therapeutic approach.
- Further research into preventative measures based on hair mechanics may be warranted.
