2C20 — Malignant neoplasms of nasal cavity
ICD-11 2C20 — Malignant neoplasms of nasal cavity
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.
The diagnosis includes nothing.
It excludes 5 items.
- Malignant neoplasm of nose NOS (2C29)
- Malignant neoplasm of olfactory bulb (2A02)
- Malignant neoplasm of posterior margin of nasal septum and choana (2B6B)
- Malignant neoplasm of skin of nose (2C30-2C3Z)
- Malignant mesenchymal neoplasms (2B50-2B5Z)
