title: [Clinico-morphological characteristics of a juvenile angiofibroma of the base of the skull].
abstract: 203 patients with juvenile angiofibroma of the base of the skull were assessed clinicoanatomically. In addition to a routine otorhinolaryngological examination 60 patients underwent computed tomography, radioangiography and thermography. Biopsy specimens obtained at operations were studied morphologically for 133 patients including application of histotopography in 15 cases and electron microscopy in 19 cases. Two clinicoanatomic forms of juvenile angiofibroma (JAF) have been revealed as well as 4 vascular types and variegation due to different combinations of vascular, cellular and fibrillar components. According to biologic nature of JAF it should be referred to fibromatoses.
