Vulvar pruritus is one of the frequent clinical symptoms in women of childbearing age and older women and is most commonly associated with various vaginal inflammatory conditions. In particular, mycobacterial infections are most common, followed by bacterial vaginosis, trichomonas vaginitis, and atrophic (geriatric) vaginitis. These different inflammatory conditions can also occur in combination. In addition, there are other causes such as vulvar squamous epithelial hyperplasia, vulvar sclerosing moss, condyloma acuminata, and local irritation and allergy. Other rare ones such as herpes, eczema, and pubic lice can also cause vulvar itching. There are also some systemic diseases that can cause itching in other parts of the body in addition to vulvar itching. For example, diabetes, severe anemia, vitamin A and B deficiency and intrahepatic cholestasis during pregnancy. In middle-aged and elderly people with untreated vulvar itching, especially those with localized lesions at the same time, they should also be alerted to vulvar malignant tumors. Of course, there are also vulvar itching that cannot be identified. Abnormal leukorrhea (vaginal discharge) is also most common with various vaginal inflammatory diseases. In addition, gonorrhea infection, mycoplasma and chlamydia infections, and cervicitis are also common causes of abnormal leucorrhea. There are also some caused by benign and malignant tumors of the genitalia. When treating vulvar itching and abnormal leucorrhea, the cause should be identified first, including gynecological examination, routine leucorrhea examination, mycoplasma and chlamydia examination, pelvic ultrasound examination and other related examinations (choose according to the need). The improvement and change of symptoms can be observed during the treatment. Vulvar itching and leucorrhea abnormalities, which often recur, not only bring physical discomfort to patients, but also a great psychological burden to them, so they should be treated promptly, effectively and thoroughly, and prevent recurrence.
