They are predominantly found in the oral mucosa, gingiva and tongue. The surface of the lesions is smooth and it varies in size. It is an asymptomatic disease caused by human papillomavirus, affecting mainly children and adolescents. In this report, we describe four cases referred to the Stomatology and Oral Surgery Department of the Faculty of Dentistry, Cartagena University with a diagnosis of focal epithelial hyperplasia. Clinical features and histopathological characteristics of the patients were recorded. We also describe the properties and advantages of trichloroacetic acid as a therapeutic method. %K Focal epithelial hyperplasia %K Papilloma virus infections %K trichloroacetic acid %U http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0719-01072012000300008
