title: [Incidental renal cell carcinoma].
abstract: OBJECTIVE
  To report the incidence and management of incidental renal cell carcinoma (RCC).
  
  
  METHODS
  We performed a retrospective longitudinal and panel study for our case series between January 1990 and December 2003. Thirty cases of RCC were analyzed, 6 of which were incidental.
  
  
  RESULTS
  4 patients were males (66.6%) and 2 females (33.3%); age ranged between 28 and 72 years. Reason for consultation was related with gastrointestinal symptoms. Ultrasound and CT scan are the most useful studies. Clinical stage was 4 T1 (66.6%), 2 T2 (33.3%). 4 radical nephrectomies and 2 conservative surgeries (partial nephrectomy and tumorectomy) were performed. A dose of 3 million units of alpha 2b recombinant interferon (IFN alpha 2b r) was given Intramuscularly two times a week over 6 months. Follow-up ranged between 120 and 60 months and none of the patients had evidence of tumor activity.
  
  
  CONCLUSIONS
  The incidence of incidental RCC in our hospital is 20%. Clinical stage was always low and survival is directly related to stage. Conservative surgery showed similar survival than radical surgery.
