title: [Localized recurrent light-induced Darier disease following Blaschko lines].
abstract: BACKGROUND
  Occurrence of localized Darier's disease was discussed. We report one case of photo-induced and localized Darier.
  
  
  METHODS
  Our patient had had a linear eruption every summer for ten years. Clinical and photological examinations showed an acantholytic dyskeratosis as well as Darier's disease. Lesions were reproduced during photobiological examinations by UVB phototests.
  
  
  CONCLUSIONS
  Several diagnoses could have been considered: Darier's disease or acantholytic dyskeratosis dermatosis as Grover's disease or Hailey-Hailey's disease or acantholytic dyskeratosis nevus. Clinical features and linear eruption following Blaschko's lines pleads for cutaneous mosaicism of Darier's disease. Photobiological explorations and literature data shows that UVB photo-induced lesions are different from isomorphic response of Koebner after irritant application.
