title: [Clinical field study on the frequency and topographical distribution of lichen ruber including the question of etiological influence factors].
abstract: A total of 374 Patients with lichen ruber of skin and/or mucous membranes, treated at our Department during a period of 7 years, have been studied retrospectively. The prevalence rate, the distribution pattern as well as the dependence on localisation of different types of clinical lesions have been examined. In 54% of the cases studied, the oral mucosa was involved, in about half of these cases without any other manifestation. In 92 hospitalised patients, a statistically significant correlation between lichen ruber and chronic hepatic disorders was revealed. On the other hand, chronic alcoholism and/or smoking habits did not show any close correlation with lichen ruber.
