Burning pain in the throat is a symptom of viral pharyngitis. The acute form of viral pharyngitis starts rapidly with the appearance of pinpoint-sized herpes in the pharynx and oral mucosa, tonsils and corners of the mouth, round or oval, isolated or clustered together, and soon ruptures to form a shallow ulcer, covered with a yellowish pseudomembrane, surrounded by bright red mucosa, accompanied by chills, fever, and burning pain in the pharynx. Etiology】 There are many kinds of pathogens, herpes virus is more common, and there are also adenovirus, coronavirus, syncytial virus and so on. When overworked, allergic quality, sudden change in temperature, cold or certain physical or chemical factors such as mercury, Kun, bismuth, iodine, etc. stimulate the body’s low resistance, it is easy to suffer from this disease. In addition, acute rhinitis, pneumonia, influenza, malaria, epidemic meningitis, etc. can be complicated by viral pharyngitis. Pathological changes] The lesions are edema and swelling of epithelial cells, causing the epidermal layer of spiny cells to bulge and form a blister containing a large number of multinucleated leukocytes and serum, with eosinophilic inclusion bodies in the nucleus. The blister quickly ruptures and forms a shallow ulcer with inflammatory cells, red blood cells or necrotic tissue on the surface. Tonsil cancer is a malignant tumor originating from the tonsil area, including tonsils, tonsil fossa, anterior and posterior pharyngeal columns and lingual tonsillar groove. 95% or more are squamous carcinoma and malignant lymphoma, while other types are rare, among which the age of cancer is 50-70 years old, while lymph node tumor is most common in young people, with the most common being 20-40 years old. The first symptom is usually a sore throat, which often radiates to the ear. Spread of the cancer to the cervical lymph nodes can cause a neck mass, which can precede other symptoms. Early symptoms are not obvious, only discomfort in the throat, foreign body sensation or mild pain. In the late stage, there is obvious sore throat, which is aggravated by swallowing and may radiate to the ipsilateral ear or face. There are often symptoms such as bad breath, bleeding and difficulty in opening the mouth. The diagnosis can be confirmed by taking tonsil tissue for pathological examination. Since alcohol consumption and smoking can cause other cancers, laryngoscopy, tracheoscopy and esophagoscopy should be performed. Viral pharyngitis Viral pharyngitis is an acute infection of the pharynx caused by a virus that occurs mostly in the pharynx, oral mucosa and surrounding skin, and can also occur in the cornea and external genitalia. The lesions are epithelial cells that are edematous and swollen, causing the epidermal layer of spiny cells to bulge and form a blister containing a large number of multinucleated leukocytes and serum with eosinophilic inclusion bodies in the nucleus. It should be differentiated from stomatitis, erythema multiforme, necrotizing stomatitis, and herpes zoster. For example, herpes zoster is an acute infectious skin disease caused by the varicella-zoster virus. Children who are not immune to this virus are infected and develop chickenpox. Some patients become infected with the virus without developing symptoms.
