The distribution of lesions in pharyngitis is limited to the localized areas of the oral cavity, such as the soft palate, palatine, and tonsils. The main common types of pharyngitis are herpetic pharyngitis, fanshawe pharyngitis, and granulocyte deficiency pharyngitis. After treatment, there is still a possibility of secondary recurrence.
1. Herpetic isthmus: acute herpetic inflammation caused by coxsackievirus A. There is still a lack of very effective antiviral drugs or vaccines, and the disease may recur when the patient’s immune function is low or resistance is reduced.
2. Fanshawe pharyngitis: it is a kind of subacute pharyngitis or tonsillitis infected by Clostridium difficile and Fanshawe spirochete, which is characterized by obvious limited inflammatory reaction and ulcer formation. These two pathogens can coexist in the oral cavity of a healthy person without causing disease, but can be induced when the body’s resistance is lowered. They can also be transmitted by sharing eating utensils, so they may recur twice after treatment.
3. Granulocyte deficiency pharyngitis: this disease is often secondary to drug poisoning, such as painkillers and sulfonamides; it can also be caused by radiation, infection and immune response. Patients sometimes have severe sore throat, and necrotic ulcers can be seen in the pharyngeal isthmus, covered with dark brown pseudomembrane, and the surrounding tissues are pale and ischemic. The soft palate and gums often have the same lesions, and secondary recurrences after treatment can also occur.
Suffering from pharyngitis, even after treatment, there is a possibility of secondary recurrence, such as the reappearance of similar discomfort, should actively seek medical treatment, follow the doctor’s instructions standardized diagnosis and treatment.
