Mucosal biopsy from lower lip for lymphocytic infiltration of the minor salivary glands showed chronic sialadenitis with evidence of epimyoepithelial islands
and fibrosis strongly suggestive of Sjogren's disease.
No centrocyte-like cells or epimyoepithelial islands
were observed in the lesions.
Further characteristics include occasional intranuclear inclusions, or Dutcher bodies; crush artifact; periductal fibrosis; and ductal metaplasia that resembles epimyoepithelial islands
