[Plexiform neurofibroma in the gingiva]

Neurofibromatosis type 1 is the most common autosomal dominant disorder of the nerve sheath and best defined phakomatosis. It usually affects skeletal system, central nervous system, eye, endocrine gland and cardiovascular system. Gingival involvement is very rare. We report radiological findings of three patients with plexiform neurofibroma who had diffuse, unilateral gingival involvement.
