olfactory neuroblastoma
(ol-FAK-tuh-ree NOOR-oh-blas-TOH-muh)
A rare type of cancer that forms in the tissues of the upper part of the nasal cavity (space inside the nose). This area is near the bone that separates the nasal cavity from the brain. These tissues are involved in the sense of smell. Olfactory neuroblastoma may spread from the nasal cavity to the bone around the eyes, the sinuses, the front part of the brain, or the lymph nodes in the neck. It is the most common type of nasal cavity tumor in children, especially in teens. Also called esthesioneuroblastoma.
