title: Verruca vulgaris and radiation exposure are associated with squamous cell carcinoma of the finger.
abstract: BACKGROUND
  Factors associated with the development of squamous cell carcinoma (SCC) of the finger are verruca vulgaris, radiation exposure, burns, and arsenic ingestion.
  
  
  OBJECTIVE
  We wish to further document the relationship between human papillomavirus (HPV) and roentgen exposure to squamous cell carcinoma of the finger.
  
  
  METHODS
  A retrospective study of 32 cases of digital squamous cell carcinoma seen at UCLA Medical Center was performed.
  
  
  RESULTS
  Ten patients (31%) had histories of verrucae at the site of the carcinoma. Eight patients (25%) had histories of x-ray therapy to the hand.
  
  
  CONCLUSIONS
  Our study further supports the association of verruca vulgaris and radiation exposure in the development of squamous cell carcinoma of the finger.
