title: Extensive focal epithelial hyperplasia: case report.
abstract: Focal epithelial hyperplasia (FEH) is a rare benign lesion caused by human papillomavirus subtype 13 or 32. The condition occurs in numerous populations and ethnic groups. A higher incidence in close communities and among family members indicates infectious pathogenesis. A 21-year-old woman with FEH is described, in whom the lesions had persisted for 10 years. A literature review is also presented, with emphasis on manifestations in the oral mucosa and histopathological features.
