title: [Diagnosis of pigment-free optic tract tumors: clinical and morphoimmunohistochemical aspects].
abstract: The authors present the results of comparison of clinical, instrumental and histological, immunohistochemical and electron microscopic data on two pigment-free ciliochoroidal tumors. Differential diagnosis was made at each of the above stages of diagnosis. There is evidence that despite the similarity of the clinical syndrome, the spindle-cell type of the histological structure of both tumors, the latter were of various histogenesis. This was confirmed by the results of immunohistochemical and electron microscopic studies. Retrospective analysis of the data of immunohistochemical and echographic studies revealed the distinctive signs that could differentiate these two types of tumors at the stage of clinical and instrumental diagnosis.
