Nasal and Paranasal Cancer

The nasal cavities are separated by the nasal septum inside the nose and open into the nasopharynx (part of the throat at the back of the nose) via the choana or nasal passage. The paranasal sinuses are located in the head behind the eyebrows and the cheeks. The lining of these structures determines the type of cancer that will affect this area. If the tissue is formed by epithelial cells such as those lining the inside of the nose, the cancer will be a few subtypes of carcinoma:

  • Squamous cell carcinoma
  • Adenocarcinoma
  • Salivary gland carcinoma
  • Melanoma
  • Olfactory neuroblastoma
  • Sinonasal undifferentiated carcinoma (SNUC)
  • Neuroendocrine carcinoma

If the tissue is non-epithelial, that is, if the cells are from deeper supporting tissues, the cancers that have their origin in it are:

  • Sarcoma
  • Lymphoma
  • Chordoma

Very rarely there are metastases from lung, kidney, breast, and ovarian cancer. (Head and Neck cancer guide)
