title: Dysplastic pointillist nevus.
abstract: BACKGROUND
  Three cases of pointillist nevus, which is a distinctive clinical type of benign melanocytic nevus with variegated pigment, have been described in the literature to date.
  
  
  METHODS
  A 24-year-old man presented with an acquired melanocytic lesion composed of multiple tiny pigmented dots. Dermoscopy revealed multiple brown globules on a reddish skin-colored background, and histologic examination demonstrated architectural disorder with cytologic atypia. Conclusion To the best of our knowledge, we report a case of dysplastic pointillist nevus.
