[Oral lichen planus and Sjogren's syndrome. 2 cases of association]

Abstract

We described two female patients, aged 55 and 49 years respectively, who fulfilled the diagnostic clinical and histological criteria for lichen planus and Sjögren's syndrome. The association of either lichen planus or Sjögren's syndrome to autoimmune disorders seems not to be fortuitous and common pathogenic mechanisms have been proposed. In the literature, however, the association between lichen planus and Sjögren's syndrome has been infrequently reported.
