Multifocal papillomavirus epithelial hyperplasia: successful treatment with CO2 laser therapy combined with interferon alpha-2b.

ABSTRACT

Human papilloma virus (HPV) infections of the oral mucosa presents with various clinical and histopathologic features in relation with the causative HPV type and chronicity and the extent of the infection.1 The entity is known by several names based on histopathologic variations such as focal epithelial hyperplasia, oral florid papillomatosis, verrucous hyperplasia, oral florid verrucosis, and Ackerman's tumor. In recent years, the term multifocal papillomavirus epithelial hyperplasia (MPVEH) has been proposed to define the variant that usually occurs in childhood and is characterized by diffuse confluent papillomatous lesions in the oral mucosa.1 Despite the lesions' benign appearance, early diagnosis and therapy of MPVEH is essential because of its high capacity for progression and its tendency for malign degeneration.
