title: Topical photodynamic therapy in verrucae. A pilot study.
abstract: BACKGROUND
  Topical photodynamic therapy (PDT) has shown good response rates in solar keratoses and superficial skin cancers.
  
  
  OBJECTIVE
  To investigate the efficiency and tolerance of PDT in refractory verrucae vulgares.
  
  
  METHODS
  In an open pilot study, 6 patients were treated with 5-aminolevulinic acid-PDT and followed up for 2 months.
  
  
  RESULTS
  One patient showed a complete response, the other 5 patients were treatment failures.
  
  
  CONCLUSIONS
  Topical PDT is probably not efficient in treating verrucae vulgares.
