2C20 Malignant neoplasms of nasal cavity

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01


From the chapter on Nasal Cavity (H&N BB) Although the nasal cavity and paranasal sinuses occupy a relatively small anatomical space, they are the site of origin of some of the more complex, histologically diverse group of tumours in the entire human body. These include neoplasms derived from mucosal epithelium, seromucinous glands, soft tissues, bone, cartilage, neural/neuroectodermal tissue, haematolymphoid cells and the odontogenic apparatus. Many of the tumours are similar to those found elsewhere in the body but a few, such as the olfactory neuroblastoma, are unique to this site.
