title: Oral lichen planus: study of 21 cases.
abstract: BACKGROUND
  Lichen planus is considered to be the most common dermatological disease involving the oral mucosa.
  
  
  OBJECTIVE
  To investigate the profile, clinical features, and the presence of dysplasia and candidiasis in patients with oral lichen planus.
  
  
  METHODS
  A total of 21 patients were selected from 258 patients at risk for oral cancer development.
  
  
  RESULTS
  Most of the patients were white (76,2%), female (66,6%), with mean age of 58.8 years. Eight were smokers and seven were alcohol consumers. The buccal mucosa was the most affected site, followed by the tongue and the gingiva. The reticular pattern was the most common appearance. Histopathology depicted dysplasia in nine cases and cytopathology was positive for Candida in eight cases in the first appointment.
  
  
  CONCLUSIONS
  Our data are similar to the literature. Cytopathology was important for the diagnosis of candidiasis. Although the presence of dysplasia was verified, further studies are necessary to clarify the importance of this finding.
