Hyperplasi i läpparnas, tungans och, mindre ofta, kindernas, munbottnens och gommens slemhinnor, i form av mjuka, smärtfria, rundade, fastsittande blåsor, 1-4 mm i diameter. Tillståndet syns oftast hos barn eller ungdomar, är familjebundet, och kan vara från flera månader till år innan det ebbar ut. Man misstänker att ett virus är orsaken, främst humant papillomvirus.
Hyperplasia of the mucous membrane of the lips, tongue, and less commonly, the buccal mucosa, floor of the mouth, and palate, presenting soft, painless, round to oval sessile papules about 1 to 4 mm in diameter. The condition usually occurs in children and young adults and has familial predilection, lasting for several months, sometimes years, before running its course. A viral etiology is suspected, the isolated organism being usually the human papillomavirus. (Jablonski, Illustrated Dictionary of Dentistry; Belshe, Textbook of Human Virology, 2d ed, p954)
