Vaginal discharge varies during the menstrual cycle and is usually white, odorless and not itchy. If a woman’s complaint is that her vaginal discharge is tofu-like and her vulva is itchy, most of the cases are considered to be mycosis fungoides. The cause of mycosis is a decrease in a woman’s resistance, which causes the normal mycobacteria present in the vagina to become pathogenic, resulting in increased vaginal discharge, tofu-like leucorrhea, and pronounced vulvar itching. The key to treating mycosis vaginalis is to improve the resistance of women, including proper exercise, trying not to stay up late at night, and eating less spicy and stimulating food, etc. It is also recommended that patients use some vaginal suppositories to relieve their symptoms of vulvar itching.
