The reports of Hollander, Ullman, Vilanova, Touraine and Baudouin, Lain and Caughron, Fitzwilliams and others who stated that they had studied cases of leukoplakia due to electrogalvanism have not appeared conclusive to us.
Only those cases of clinical leukoplakia that were confirmed by a microscopic diagnosis have been considered by us to be true leukoplakia.
