The differences between nasopharyngitis and nasopharyngeal carcinoma are very clear. Firstly, nasopharyngitis is an acute inflammatory irritation, while the cause of nasopharyngeal carcinoma is currently unknown, generally associated directly with EB virus infection. Secondly, their clinical manifestations are different. Patients with nasopharyngitis may experience dryness and pain in the nasopharyngeal area, and yellow secretions may occur when clearing the throat in the morning. In contrast, nasopharyngeal carcinoma typically presents as a painless mass. During examination with a nasopharyngoscope, the surface of nasopharyngitis is congested and swollen, whereas in nasopharyngeal carcinoma, cauliflower-like neoplasms or ulcers can be found at the top of the nasopharynx or near the pharyngeal recess. A local pathological examination can reveal symptoms and clarify the diagnosis. In terms of treatment, nasopharyngitis requires symptomatic anti-inflammatory treatment, while nasopharyngeal carcinoma requires local radiotherapy or chemotherapy.
