[Osteo-hypertrophic angiodysplasia with oromaxillofacial localization. A report of a clinical case and a review of the literature].

: The authors report a case of oro-facial port-wine stain angiomatosis with cutaneous and mucosal lesions localized in the first and the second branch surface distribution areas of the left trigeminal nerve in association with left upper lip, cheek and hemimaxillary true hypertrophy leading to a severe dento-skeletal malocclusion with open-bite and facial asymmetry. The authors through a revision of the literature locate nosologically this case among the rare congenital angiodysplastic syndromes affecting the maxillo-facial district as the Sturge-Weber and the Klippel-Trenaunay syndromes. They debate also about etiopathogenetic, clinical, differential diagnosis and therapeutic aspects concerning the management of patients affected by this kind of malformation.
