Glioma
Glioma is a solid tumour which may present externally at the root of the nose which becomes broadened, or it may appear intranasally from the roof or lateral wall of the nasal cavity. It arises from a failure of the dural process to become sealed off in the foramen caecum during embryonic development. The external tumour is subcutaneous, firm and elastic to the touch, and it must be distinguished from a dermoid cyst. The intranasal type resembles a small nasal polypous or inspection and it appears in the nasal vestibule. It is firm to touch with a probe and does not enlarge when the baby cries, a fact which distinguished it from an encephalocele. The glioma is composed of neuroglial tissue and astrocytes and is not malignant. It should be removed completely.
