The clinical distinction between rhinitis and nasopharyngeal cancer mainly includes the following points: 1. The symptoms of the two are different. Rhinitis mainly manifests as nasal congestion, runny nose, sneezing and other related symptoms, which are very common. It is rarely accompanied by nose bleeding. In the early stage of nasopharyngeal cancer, the symptoms of the nose may not be obvious, and there may be blood in the retraction of the nose. The patient may have recurrent unilateral secretory otitis media in the early stage, and painless mandibular angle lymph nodes may occur. Swelling and other related changes, the patient may lose weight. Only when the nasopharyngeal cancer increases significantly can the patient experience poor ventilation around the nose. 2. Clinical examination is different. Rhinitis mainly manifests as turbinate hypertrophy, nasal mucosal congestion and other related changes. Nasopharyngeal cancer mainly manifests as the proliferation of new organisms on the posterior wall of the nasopharyngeal roof or pharyngeal crypts, with surface changes such as ulcers, cauliflower-like, and infiltrative growth. Some patients may also show submucosal hyperplasia and bulge changes. 3. CT examination is different. During CT examination, rhinitis mainly manifests as changes in turbinate hypertrophy and bone hyperplasia, while nasopharyngeal cancer can manifest as disappearance of fat spaces, fullness of unilateral pharyngeal crypts, soft tissue hyperplasia, etc. 4. Pathology is different. Rhinitis pathology shows inflammatory tissue, while nasopharyngeal cancer pathology can clearly show cancer tissue.
