[Nasal glial heterotopia: Clinical and morphological characteristics]

The paper describes a case of nasal glial heterotopia in a 10-month-old girl with a mixed (intranasal and subcutaneous) localization, which is accompanied by the divergence of the nasal bones. Histological examination supplemented by immunohistochemical reactions with antibodies to vimentin, S100 protein, neuron-specific enolase, as well as Ki-67 and smooth muscle actin confirmed the neural nature of the tumor. Fields of mature astrocytic glia including individual cells with neuronal differentiation were found among the fibrous and fibrovascular tissues. The paper provides a brief overview of the discussed pathology.
