title: Late recurrence of ovarian granulosa cell tumor at the retroperitoneal and renal hilum level in a single-kidney patient--case report.
abstract: BACKGROUND
  Ovarian granulosa cell tumors are rare tumors characterized by a long natural history and a tendency to late recurrence. Surgical resection, radiotherapy, chemotherapy and hormone therapy are possible options to treat recurrent disease. The choice will depend on the patient's condition and the site of recurrence.
  
  
  METHODS
  We describe the case of a 72-year-old patient with a single left kidney who presented retroperitoneal recurrence of ovarian granulosa cell tumor at the left renal hilum ten years after primary treatment.
  
  
  CONCLUSIONS
  This case illustrates an example of very late recurrence and emphasizes the importance of extended follow-up for these patients.
