What's wrong with throat polyp?

Suggestion: Hello! Throat polyp: refers to the redundant tumor growing on the surface of throat tissue. Modern medicine usually refers to the vegetation growing on the surface of human mucosa as polyps. Nasal polyp is not a real tumor, and it is often the result of allergic reaction and nasal mucosal edema caused by chronic inflammation of sinus. Microscopic examination showed that nasal polyps were not completely identical in tissue structure, and they were divided into three types: (1) allergic polyps. It is often bilateral. If the cause of allergy cannot be eliminated, polyps will recur after resection. In addition to obvious edema, there are a large number of eosinophils infiltrating, and the basement membrane of the mucosa is obviously thickened (glassy) and epithelial metaplasia. (2) Inflammatory polyp. Unilateral or single polyp formation, mostly caused by local infection, is not easy to recur after resection. The edema is slight, and the inflammatory cells exuded are mainly neutrophils and monocytes. Epithelial metaplasia and basement membrane thickening are rare and can be distinguished from allergic polyps. (3) Polyps in the retronasal foramen. This is a clinical name, because polyp has a long pedicle, which extends from the nasal cavity through the posterior hole into the nasopharynx. In fact, acute or allergic nasal mucosal edema does not heal for a long time, and the lesions are mainly inflammatory edema and inflammatory infiltration, without interstitial degeneration and hyperplasia, so nasal polyps belong to inflammatory lesions. However, because nasal polyps form masses, they are often called tumor-like lesions, but in fact they generally do not become malignant. Nasal polyps are sometimes very large, even up to several centimeters in size, filling the nasal cavity, leading to nasal congestion, poor breathing, or valve-like opening and closing. Nasal polyps are often accompanied by symptoms such as dysosmia, headache, and excessive nasal sound when speaking. Nasal congestion leads to secretion retention, which can induce sinusitis. At this time, many secretions are purulent. Huge nasal polyps can completely fill the nasal cavity and even push the nasal bones outward, changing the shape of the nose.
