title: [Frequency of occurrence of eyelid basal cell carcinoma in the centralwest region of São Paulo State and carriers characteristics].
abstract: OBJECTIVE
  To observe the frequency of occurrence of eyelid basal cell carcinoma in the centralwest region of São Paulo State and to describe the demographic profile of the basal cell carcinoma carriers.
  
  
  METHODS
  Transversal study, using a random sampling, carried out in 12 cities in the centralwest region of São Paulo State evolving 11,167 individuals. Patients were evaluated in a Mobile Unit, with complete ophthalmologic evaluation. The diagnosis of eyelid basal cell carcinoma was done through clinical examination and biomicroscopy of the lesion if desirable. The basal cell carcinoma carriers diagnosed were referred to Oculoplastic Clinic of Faculdade de Medicina de Botucatu for treatment. Data were submitted to analysis of frequency of occurrence.
  
  
  RESULTS
  Five cases of eyelid basal cell carcinoma were identified in the sample, corresponding to a frequency of occurrence of 0.045%. Four patients were female, most with age equal or greater than 70 year-old and all the cases had white skin color. Only three individuals conveyed attended the service for excision of the lesion and diagnostic confirmation.
