title: Erythroplasia of Queyrat with urethral involvement: treatment with carbon dioxide laser vaporization.
abstract: BACKGROUND
  Erythroplasia of Queyrat is an uncommon carcinoma in situ that usually arises on the mucosa of the glans penis or prepuce as red, shiny, sharply demarcated velvety plaques. The treatment is often difficult and associated with significant recurrence rates, especially in cases with urethral involvement.
  
  
  OBJECTIVE
  To evaluate carbon dioxide laser treatment in a case of erythroplasia of Queyrat with urethral involvement.
  
  
  METHODS
  We report a patient with erythroplasia of Queyrat involving the urethra who was treated with carbon dioxide laser vaporization.
  
  
  RESULTS
  Treatment with carbon dioxide laser vaporization resulted in an excellent cosmetic and functional status outcome for the glans penis and urethral lesions.
  
  
  CONCLUSIONS
  Carbon dioxide laser vaporization is probably the initial elective treatment for erythroplasia of Queyrat with urethral involvement in young immunocompetent patients. A follow-up is necessary, and new sessions of treatment should be quickly performed if recurrence occurs.
