Circumferential perianal pilonidal sinuses
Diseases of the Colon and Rectum
|February 1, 1984
Abstract:
Two cases of recurrent perianal suppuration are described in which the underlying pathology is believed to be pilonidal sinus disease affecting the perianal skin directly. This has given rise to intersphincteric fibrosis and, in one case, a subcutaneous track almost completely encircling the anus. The pathogenesis of the condition and its possible relationship to previous surgery are discussed.
Insights
Pilonidal sinus disease can directly affect perianal skin, causing recurrent suppuration and anal fibrosis. This condition may be linked to prior surgical interventions, impacting anal structures.
Area of Science:
- Proctology
- Dermatology
- Surgical Pathology
Background:
- Recurrent perianal suppuration presents a diagnostic challenge.
- Pilonidal sinus disease typically affects the sacrococcygeal region.
- Understanding atypical presentations is crucial for effective management.
Observation:
- Two cases of recurrent perianal suppuration were analyzed.
- Pilonidal sinus disease was identified as the underlying pathology in both cases.
- The disease directly impacted the perianal skin, leading to complications.
Findings:
- Intersphincteric fibrosis was observed as a consequence.
- A subcutaneous track encircling the anus developed in one patient.
- Direct perianal skin involvement by pilonidal sinus disease is a rare occurrence.
Implications:
- This presentation broadens the differential diagnosis for perianal suppuration.
- Previous surgery may play a role in the pathogenesis of this condition.
- Further investigation into the relationship between pilonidal sinus disease and perianal pathology is warranted.
