ABSTRACT: Pilonidal disease is one of the most frequent entities in our daily surgical activity. Although it is a benign disease, malignant degeneration is likely to occur in pilonidal disease. We reviewed surgical interventions for pilonidal diseases performed from January 1, 1995 to December 31, 2008. We reviewed all 3729 histology reports obtained after surgical removal of pilonidal disease. There were three cases of squamous cell carcinoma and one case of basal cell carcinoma. Patients affected by squamous cell carcinoma had a mean age of 54.2 years and a mean time of evolution of the lesions of 20.6 years. We found local recurrence and lymph node recurrence. Mean follow-up period was 5 years and there was no mortality. The patient with basal cell carcinoma had 1 year of pilonidal disease evolution. There were no recurrences. Malignancy can arise in pilonidal diseases with a long evolution time. There is a high rate of recurrence and morbimortality in cases of squamous cell carcinomas. Adjuvant radiotherapy in addition to complete local excision has demonstrated a decrease in the rate of local recurrence.Cirugia y cirujanos 07/2011; 79(4):346-50. · 0.18 Impact Factor
