title: [Retinoblastoma: morphologic, ultrastructural and scanning electron microscopy study].
abstract: We present a clinical and morphological study of one case of unilateral Retinoblastoma in a boy two years of age. There were no family antecedents. Cellular morphology and histological organization were studied with particular reference to rosettes and the angiogenic capacity of the tumor. Scanning electron microscopy permitted the definition of the surface organization and infiltration pattern together with tridimensional characteristics of the Rosettes. We also discuss the neuroectodermal origin of the neoplasm.
