Geographical Aspects of Oral Focal Epithelial Hyperplasia

Abstract
During the last 10 years an increasing number of cases of focal epithelial hyperplasia have been published from different parts of the world. We are not yet able to map out satisfactorily the geographic occurrence of the disease, but it is already evident that focal epithelial hyperplasia is more common among Eskimos and American Indians than in most other population groups. Only single cases have been described among Caucasians in America, Europe and the Middle East, among Negroes in Africa and among aborigines in Australia and Polynesia. No cases have been published so far occurring in the Far East.
