Focal epithelial hyperplasia in a Turkish family.

Focal epithelial hyperplasia (FEH) is a benign proliferative condition that is more frequently found in children of certain ethnic groups. Human papillomavirus (HPV) 13 and 32 genotypes has been consistently detected in these lesions. In this study a daughter, mother and father had FEH, and HPV 13 was shown by sequence analysis in the lesions of these patients. Cryotherapy was applied to the lesions and the lesions improved, but did not recover properly. In conclusion, HPV genotyping should be performed in FEH cases.
