Electron microscopic observation on the epithelial-connective tissue junction of pemphigus vulgaris. A case report

An electron microscopic observation on the erosive buccal mucosa of a buccal mucosa of a patient with typical pemphigus vulgaris was carried out. The ultrastructural features of the basal cells and the basal lamina in the advanced oral lesion varied from section to section of the biopsy specimen. The basal lamina showed various morphologic alterations indicating the presence of both destructive and regenerative processes in different sections. The filamentous bodies were also observed both in the basal cell layer and in the upper lamina propria.
