First of all, it is clear that lymphatic hyperplasia in nasopharynx is definitely not nasopharyngeal cancer. Typical symptoms of nasopharyngeal cancer include blood in the nose, nosebleed, stuffy ears, tinnitus, nasal congestion, headache on one side, and even accompanied by enlarged lymph nodes in the neck. Signs of nasopharyngeal cancer are the pharyngeal crypt on one side, and there are also a few cauliflower-sized occupations and ulcers in the middle of the nose, that is, in the posterior wall of the nasopharyngeal apex, which are typical protruding lumps. There are also early cases that are not very typical, but can also manifest as mucosal protrusions. This mainly depends on biopsy and pathology to confirm the diagnosis. Nasopharyngeal cancer is generally non-keratinized squamous epithelium, that is, squamous cell carcinoma, and the degree of differentiation is also divided into moderately differentiated, highly differentiated, poorly differentiated and undifferentiated, and the degree of malignancy is also different. As for the lymphatic tissues in nasopharynx, because the whole area is called endolymphatic ring, the whole nasopharynx, palatine tonsils, that is, inflamed tonsils, and follicles at the root of the tongue, including lateral pharyngeal cords, as well as lymph nodes of the pharyngeal tympanic tube and pharyngeal larynx, all of these belong to endolymphatic ring, which belong to the immune tissues, lymphatic tissues of the human body. Lymphoid tissues in these areas can proliferate, like lymphoid follicles in the posterior wall of the pharynx, hyperplasia of the tonsils, hyperplasia of the follicles in the root of the tongue are all lymphoid hyperplasia, including the nasopharynx can also have lymphoid hyperplasia. Even in adults, when the adenoids of childhood have atrophied and have not completely atrophied away, there may be some adenoids remaining. If this is the case, the clinical suspicion is high, also take a biopsy to identify, this time should be reported in the squamous epithelium of the ordinary chronic inflammation, lymphoid hyperplasia or hyperplasia active, this is generally not cancer. Unless it is high-grade intraepithelial neoplasia, that is, the original pathology described as severe atypical hyperplasia, is inclined to precancerous lesions.
