Malignant transformation can occur in long-standing pilonidal disease, particularly squamous cell carcinoma, which shows high recurrence rates. Adjuvant radiotherapy may reduce local recurrence after surgical excision.
Area of Science:
- Oncology
- Dermatology
- Surgical Pathology
Background:
- Pilonidal disease is a common surgical condition with a potential for malignant degeneration.
- This study reviews surgical interventions for pilonidal disease between 1995 and 2008.
- Malignant transformation in pilonidal disease, though rare, necessitates careful histological examination.
Observation:
- A review of 3729 histology reports identified three cases of squamous cell carcinoma (SCC) and one case of basal cell carcinoma (BCC).
- SCC cases presented with a mean lesion evolution of 20.6 years and showed local and lymph node recurrence.
- The BCC case had a 1-year evolution and no recurrence.
Findings:
- Malignancy, especially SCC, can arise in pilonidal disease with prolonged evolution.
- SCC in pilonidal disease is associated with significant recurrence and morbidity.
- No mortality was observed in the reviewed cases.
Implications:
- Early detection and complete surgical excision are crucial for managing pilonidal disease with suspected malignancy.
- Adjuvant radiotherapy can decrease local recurrence rates for squamous cell carcinoma.
- Long-term follow-up is essential for patients with pilonidal disease, particularly those with chronic lesions.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
