title: Non-melanoma skin cancer in renal transplant recipients: a study in a Brazilian reference center.
abstract: BACKGROUND
  Non-melanoma skin cancer (NMSC) after kidney transplantation is common and can result in significant morbidity and mortality. Their incidence and risk factors in renal transplant recipients (RTRs) vary depending on geographic location and there is a scarcity of literature describing the features of NMSC in Brazil.
  
  
  METHODS
  NMSC data were retrospectively reviewed in charts of RTRs at the Clementino Fraga Filho University Hospital from January 2004 to December 2005, with the objectives of: 1) evaluating the occurrence of NMSC in RTRs transplanted between 2004 and 2005 at a reference center in Brazil; 2) verifying the frequency of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) in these patients according to sex, race, age, and tumor site; and 3) determining the time between transplantation and neoplasia.
  
  
  RESULTS
  We found 202 RTRs, with 165 suitable for the study. There were 19 NMSC in eleven patients (6.67%), at a mean time of 37.7 months after transplantation. The mean follow-up time was 72.7 months. The ratio of SCC:BCC was 1.1:1. White race and age ≥40 years were associated with a higher incidence of NMSC and they appeared predominantly in sun-exposed sites.
  
  
  CONCLUSIONS
  Regular dermatological follow-up of RTRs can help to make earlier diagnoses, resulting in better quality of life and lower morbidity and mortality.
