Superficial, transitional and polygonal buccal epithelial cells from patients with the erosive type of lichen planus were compared with similar cells from non-keratinizing human buccal mucosa. Transitional cells from non-keratinizing buccal mucosa had glycogen lakes and membrane-coating granules with electron dense cores. Surface cells were not keratinized and pathological cells were less granular. In lichen planus membrane-coating granules were numerous, markedly electron dense, and some showed an internal lamellar structure. Surface cells were keratotic or parakeratotic. Processes of macrophages were associated with the pathological membrane-coating granules.
