Nasal Glioma

Abstract
|
|
|
Nasal gliomas are rare, benign, congenital tumors which are thought to be the result of an error in embryonic development. They have the same type of origin as encephaloceles but the meningeal continuity has closed, resulting in "vestigial encephaloceles". They are found in both sexes with a slight male predominance. They are 60% extranasal and 30% intranasal. The rest are mainly combined defects. In 20% of the cases, there is a mainly fibrous connection to the intracranial space.Clinically they are firm, noncompressible, nonpulsatile, gray or purple tumors obstructing the nasal cavity intranasally and causing nasal deformity extranasally. Histologically they are composed of astrocytic neuroglial cells interlaced with fibrous and vascular connective tissue covered by skin or nasal respiratory mucosa. Surgical extirpation of the extracranial portion of the tumor is the treatment of choice.
Here I report a case of nasal glioma in 2 years old male patient arised from the right lateral sice of the nose, with review of the literatures.
