Verrucous carcinoma (Buschke-Lowenstein) arising in a sacrococcygeal pilonidal sinus tract: report of a case.
OBJECTIVE
Pilonidal sinus disease is usually located in the sacrococcygeal region. Verrucous carcinoma (Buschke-Lowenstein) is a rare variant of squamous cell carcinoma with distinct clinical and histopathologic features, with a favorable prognosis. Malignant degeneration is an infrequent complication, which is associated with a high recurrence rate and poor prognosis.


METHODS
A case report is presented.


RESULTS
We report a 48-year-old man with a 10-year history of recurrent pilonidal sinus disease presented with a sacrococcygeal verrucous carcinoma arising in the pilonidal sinus tract and associated with good prognosis. After operation, a 5-year disease-free follow-up was observed.


CONCLUSIONS
Careful inspection of the pilonidal area in all chronic and long-standing inflammatory processes is important and should be evaluated for malignant transformation.
