title: [Radiologic similarity and dissimilarity of Histiocytosis X in the mandible between non adult and adult]
abstract: 28 cases of Histiocytosis X in the mandible were divided into two groups:the non adult group (19 cases,21 foci).and the adult group(9 cases,12 foci).their similarity and dissimilarity in radiological appearances were contrasted individually.The authors consider there were different roentgenographic manifestations between the two groups according to the diversity of physilological and morphological configuration in the mandible.The former group which had its characteristic roentgenologic feature displayed a radiolucent region with an irregular margin mostly accompanied with a periosteal reaction at the inferior and lateral surfaces of the mandible.Owing to lacking above mentioned demonstration,it was difficult to distinguish the lesions of later group from other disease in the mandible.
