[Nasoglioma: apropos of 2 cases].

Two cases of nasal gliomas, which are rare ectopic rests of glial tissue found at the root of the nose, are presented. It is important to distinguish nasal tumors from basofrontal encephaloceles to avoid inadvertent exposure of the brain during an inadequate surgery. Because of their related embryologic origins, the distinction between nasal gliomas and basofrontal encephaleces may not be clear clinically. Nasal gliomas may be treated by several surgical specialties to avoid iatrogenic complications and recurrence.
