title: Kerinokeratosis Papulosa of Childhood.
abstract: BACKGROUND
  Kerinokeratosis papulosa (KP) is considered an extremely rare genodermatosis presenting usually as waxy papules on the trunk in childhood.
  
  
  OBJECTIVE
  To describe and analyze the clinical, histological and potential etiopathological aspects of KP.
  
  
  METHODS
  The dermatoscopic features of a new case of KP of childhood are investigated. The presence of human papillomavirus (HPV) DNA in lesional skin was studied by polymerase chain reaction. Furthermore, all cases of KP of childhood reported so far were reviewed.
  
  
  RESULTS
  As a diagnostic tool, we describe for the first time a dermatoscopic feature, namely a cribriform pattern of KP, in an 11-year-old boy. In addition, we detected HPV (type 57) in his KP lesions.
  
  
  CONCLUSIONS
  Dermatoscopic examination might be a useful tool to distinguish KP from other skin lesions, e.g. common warts. The detection of HPV type 57 might hint to an etiological role of HPV for KP.
