The presence of white stuff in the vagina is considered to be an intravaginal discharge, which needs to be combined with the nature of the discharge to determine if there is a pathological cause. Under normal circumstances, there is a small amount of vaginal discharge that is white or milky and odorless, which is a normal physiological phenomenon. If the vaginal discharge is increased, white curd-like or tofu-like, and accompanied by vulvar and vaginal itching, it is mostly caused by mycosis fungoides, which can be diagnosed by routine leucorrhoea examination. In this case, the vulva and vagina should be washed with an alkaline solution, and antifungal treatment should be given by intra-vaginal dacrynic pessary or mycophenolate tablets. Bacterial vaginitis can also be caused by bacterial infection, which is a white, uniform vaginal discharge with a fishy odor. Therefore, when a woman has a white vaginal discharge, she should be examined and treated promptly.
