title: [Seborrheic keratosis erupting in a tattoo].
abstract: BACKGROUND
  Decorative tattoos have been associated with inflammatory reactions and transmission of infectious diseases. Cutaneous tumors have rarely been reported.
  
  
  METHODS
  We report the case of a 26-year-old man who presented eruptive seborrheic keratoses strictly localized on the area of a decorative tattoo. No other lesion was present anywhere else on the cutaneous surface. Three years later the lesions remained stable.
  
  
  CONCLUSIONS
  To our knowledge, this is the first report of eruptive seborrhelc keratoses on a tattoo. In our observation, the role of human papillomavirus contamination during tattoo procedure is discussed.
