Nasopharyngeal cancer mass mostly occurs in the parietal wall and lateral wall of nasopharynx, among which the pharyngeal crypt is the most favorable site. In early stage, nasopharyngeal cancer can be manifested as localized mucous membrane protrusion, and with further development of lesion, it can form cauliflower pattern, nodular, ulcerative and other related changes, and some patients can also manifest submucosal protrusion, which is difficult to be distinguished, and it is sometimes difficult to take out positive results when taking pathological biopsy for several times. Further invasion of nasopharyngeal cancer mass can involve intracranial area, and further forward invasion can also involve sinuses, such as sieve sinus and pterygoid sinus, and compression of nasopharyngeal cancer mass on the pharyngeal opening of the Eustachian tube can lead to secretory otitis media, which is a relatively common early symptom. Nasopharyngeal cancer can invade deep upper cervical lymph nodes through lymph nodes, which is manifested as enlarged lymph nodes in mandibular angle area, and with further development of the lesion, it can invade contralateral lymph nodes.
