title: Dermatological manifestations in hepatitis B surface antigen carriers in east region of Turkey.
abstract: METHODS
  Various cutaneous disorders associated with hepatitis B virus infection have been reported so far. Almost all of them were some peculiar eruptions or some disorders mainly based on immune complex reaction.
  
  
  OBJECTIVE
  The aim of this study was to compare the frequency of all dermatological disorders other than genetic ones in hepatitis B surface antigen (HBsAg) carrier patients and controls in our geographical area.
  
  
  METHODS
  Examinations were made on 88 hepatitis B carriers and 84 control patients, including entire skin surface, and oral and anogenital mucosa, and all the manifestations that could be seen were noted down.
  
  
  RESULTS
  While the number of HBsAg carrier patients with dermatological disorders was 62 (70.75%), it was only 24 (28.57%) in control patients. This seems statistically important: Yates' corrected chi-square test = 28.5; P = 0.0000001; odds ratio = 6.0 (2.94 < odds ratio < 12.2). The prevalence of oral lichen planus and pitted keratolysis in HBsAg carrier group was significantly higher than that of controls. We found the duration of positivity was not important statistically in the development of the dermatological disorders.
  
  
  CONCLUSIONS
  HBsAg positivity may induce or cause proneness to oral lichen planus and pitted keratolysis with some mechanism that needs to be elucidated.
