title: Posttraumatic proliferating trichilemmal tumour on the frontal region of the scalp: a case report.
abstract: BACKGROUND
  Proliferating trichilemmal tumour defined with more than one terms by many author, after well documentated series reported as "proliferating epidermoid cysts" by Wilson-Jones, firstly in 1966. They are rare, slowly growing, lobular masses inherited autosomal dominantly and localized on scalps of older women and believed to arising as a complication of a trauma and inflammation and effect 5-10% of people.
  
  
  METHODS
  We intented to present the case of a 62 years old Turkish woman with a history of slowly growing scalp mass after the trauma, especially during last 15 years. After surgical evaluation, histopathological slides exhibited the characteristic structures of proliferating trichilemmal tumour. The patient was lost to follow-up and no recurrens or distance metastasis detected during 40 months follow-up.
  
  
  CONCLUSIONS
  In our opinion, widely surgical excision with long-term surveillance is the best choice for both diagnosis and treatment still today.
