ESTHESIONEUROBLASTOMA

ALTERNATE NAMES

Olfactory Neuroblastoma; Skull Based Olfactory Neuroblastoma; Intracranial Olfactory Neuroblastoma; Recurrent Esthesioneuroblastoma

DESCRIPTION

Esthesioneuroblastoma is a rare cancer of the upper part of the nasal cavity called the cribriform plate, which is a bone deep in the skull between the eyes, and above the ethmoid sinuses. It develops in nerve tissue associated with the sense of smell and can occur in people of any age. This cancer is very uncommon, accounting for 7 percent of all cancers of the nasal cavity and paranasal sinuses. Although it generally grows slowly, an esthesioneuroblastoma can sometimes grow very quickly. Fast-growing tumors can metastasize (spread) even many years after treatment of the initial tumor.

DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM CODING

Diagnostic testing: Physical examination of the eyes, nose and throat; Endoscopy examination of the mouth and nose; CT, MRI or PET scan; biopsy; or laboratory testing of the blood and urine.

Physical findings: Symptoms and signs of this type of tumor may include nasal obstruction; nosebleeds (epistaxis); changes in the sense of smell (hyposmia); nasal discharge (pus); facial pain; changes in vision; excessive tearing from the eyes (lacrimation); facial or tooth numbness; ear pain or pressure; enlarged lymph nodes in the neck; and difficulty opening the mouth.

ICD-9: 160.0

ONSET AND PROGRESSION

Esthesioneuroblastoma usually begins in the part of the brain that interprets smell (olfactory bulb). This tumor may occur at any age, and tends to form behind the nose and may affect the sinuses. People with olfactory neuroblastomas may lose the sense of smell, have frequent nosebleeds, and may experience difficulties breathing through their nose.

TREATMENT

Esthesioneuroblastomas are treated with surgery, radiation, and chemotherapy depending on the response to treatment and metastasis. These treatments may affect eating, speaking, or breathing.
