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.
