Three patients with focal epithelial hyperplasia Heck are presented. In two cases biopsies were made and investigated biochemically and by electron microscopy. In one case typical papillomavirus and HPV 1-DNA could be demonstrated, in the other the attempts of isolation failed. Virologic results and epidemiologic considerations suggest a viral etiology of focal epithelial hyperplasia Heck, but they are not sufficient to prove this.
