So-called nasal glioma: case report with immunohistochemical study.
The so-called nasal gliomas (nasal cerebral heterotopias) are rare, congenital, benign masses of neurogenic origin with intra or extranasal location, or both. An intranasal case is reported in a 7-month-old infant who successfully underwent surgery with the intranasal approach. The tumor had no intracranial extension and the child is free of disease after a three-year follow-up. Immunohistochemical study confirmed the glial (GFAP+) and neuronal (NSE+) nature of the cells composing the mass. In addition to the clinical behavior, the benign nature of the tumor is also indicated by the negativity of Ki67 (MIB-1) and p53 proliferation markers as well as by CD44 negativity. As far as we know, this is the first reported case of nasal glioma subjected to immunohistochemical investigation of proliferation activity.
