White matter in the vagina should refer to leukorrhea, which can be physiological or pathological. In women of childbearing age, there will be a little leucorrhea in the vagina that is clear, transparent, odorless and does not cause vulvar itching symptoms, which is a normal physiological phenomenon. If the leucorrhea in the vagina is increased, white curd-like or bean curd-like, it is often mycosis fungoides caused by Pseudomonas infection, and the vulvar itching symptoms will be more severe, and a routine leucorrhea examination can be performed. It is often seen in patients with broad-spectrum antibiotics, pregnant women, and women with diabetes. It is recommended to stop using antibiotics, control blood sugar, keep the vulva clean and dry, and wear loose, cotton underwear. Treatment with clotrimazole suppositories or dacrynic acid suppositories inserted intravaginally and dacrynic acid ointment applied externally. Alternatively, leucorrhea caused by bacterial vaginitis may be increased, homogeneous and fishy smelling, and can be treated with metronidazole pessary intravaginal insertion.
