title: Multifocal papilloma virus epithelial hyperplasia.
abstract: Multifocal papilloma virus epithelial hyperplasia is an infection of the oral mucosa produced by human papilloma virus types 13 and 32, which primarily bilaterally affects lips, lateral borders of tongue, and buccal mucosa. The attached oral mucosa, floor of mouth, soft palate, and oropharynx are sites that appear not to be affected. This study comprises 110 patients with multifocal papilloma virus epithelial hyperplasia identified over a period of 3 years in Guatemala City and neighboring rural areas. All but four patients were younger than 18 years of age. More than one affected patient was observed in several families. All but three cases occurred in patients living in extreme poverty (annual family income less than $1,200 in U.S. dollars). Biopsies of 60 lesions demonstrated acanthosis and nuclear degeneration within the epithelium. We suggest that the eponym Heck's disease be abandoned because this disease was described in the Latin-American literature before the initial description in the American literature. We propose the term multifocal papilloma virus epithelial hyperplasia, which best describes the nature and multifocality of this disease.
