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