Abstract:
In 2 children (brother and sister) focal epithelial hyperplasia could be diagnosed by means of histology, human papillomavirus typing and Southern blot. In the 14-year-old girl the history could be followed over many years. The high familial incidence and the special geographic distribution of focal epithelial hyperplasia are pointed out.
