title: Dermoscopy of scalp tumours: a multi-centre study conducted by the international dermoscopy society.
abstract: BACKGROUND
  Little is known about the dermoscopic features of scalp tumours. Objective  To determine the dermoscopic features of scalp tumours.
  
  
  METHODS
  Retrospective analysis of dermoscopic images of histopathologically diagnosed scalp tumours from International Dermoscopy Society members.
  
  
  RESULTS
  A total of 323 tumours of the scalp from 315 patients (mean age: 52 years; range 3-88 years) were analysed. Scalp nevi were significantly associated with young age (<30 years) and exhibited a globular or network pattern with central or perifollicular hypopigmentation. Melanoma and non-melanoma skin cancer were associated with male gender, androgenetic alopecia, age >65 years and sun damage. Atypical network and regression were predictive for thin (≤1 mm) melanomas, whereas advanced melanomas (tumour thickness > 1 mm) revealed blue white veil, unspecific patterns and irregular black blotches or dots.
  
  
  CONCLUSIONS
  The data collected provide a new knowledge regarding the clinical and dermoscopy features of pigmented scalp tumours.
