Recurrent squamous-cell carcinoma arising in sacrococcygeal pilonidal sinus tract: report of a case and review of the literature.

PURPOSE

Carcinoma arising in a pilonidal sinus is a rare complication. This study reports the case of a patient with recurrent squamous-cell carcinoma arising in a sacrococcygeal pilonidal sinus tract.

METHODS

This patient was treated with a wide local excision and mesh grafts. Three months later the patient was treated with adjuvant radiation therapy.

RESULTS

The patient died two years later from recurrence in inguinal lymph nodes, liver, and lungs.

CONCLUSION

Some authors propose consideration of treatment with adjuvant chemotherapy and radiation therapy in addition to complete local excision as a possible means to decrease the local recurrence rate.
