title: [Association of lichen sclerosus and monomelic scleroderma].
abstract: BACKGROUND
  Coexistence of lichen sclerosus and scleroderma is well demonstrated. However, clinical and histological lesions of lichen sclerosus and scleroderma, in a linear pattern, do not seem to have been reported.
  
  
  METHODS
  We report the case in a six years old boy, of both lichen sclerosus and linear scleroderma lesion that involved his left lower limb. Immunological and inflammatory investigation was normal or negative, as well as, bone and muscles analyze of the leg. Further outcome was benign.
  
  
  CONCLUSIONS
  This new case confirms the possibility of an association, inside a same limb, of lichen sclerosus and localized scleroderma, and supports the concept of a common etiological process in these two diseases. In an other hand, it could reflect the possibility of two distinct clinical expressions of the same pathogenic process.
