Itching around anus and vulva caused by pinworm usually occurs at night. (2) Chronic vulvar malnutrition: pruritus is the main symptom, accompanied by vulvar skin whitening. (3) Drug allergy or chemical stimulation: soap, condoms, bromogeramine, etc. Contact or allergic dermatitis may be caused by direct stimulation or allergy, and symptoms of vulvar itching may occur. (4) Bad hygiene habits: If you don't pay attention to the local cleaning of the vulva, sebum, sweat, menstrual blood, vaginal secretions, and even urine and feces are soaked, and long-term stimulation of the vulva can cause itching; Using unclean menstrual belt during menstruation and wearing airtight chemical fiber underwear at ordinary times will induce itching due to damp-heat stagnation. (5) Other skin lesions: abrasions, common warts, herpes, eczema and tumors can all cause vulvar itching. 2. Systemic diabetes (1): Due to the stimulation of diabetes to vulva skin, especially when accompanied by candidal vulvitis, vulva itching is serious. Many patients first went to the hospital because of pruritus and redness of vulva, and were diagnosed as diabetes after further examination.

At present, some scholars think it may be related to mental or psychological factors. The clinical manifestations and diagnosis of vulvar pruritus are mostly located in clitoris and labia minora, and can also spread to labia majora, perineum and even perianal lesions, which are often paroxysmal or persistent and worsen at night. The degree of itching varies significantly with diseases and individuals. Long-term scratching can cause skin hypertrophy and lichenoid changes. The itching caused by crabs is mostly confined to pubic hair and its vicinity, and scratching can cause scratches, blood scabs or secondary folliculitis. Look carefully for gray crabs about 1 ~ 2 mm long scattered between pubic hair. Unexplained vulvar pruritus generally only occurs in women of childbearing age or postmenopausal women, involving the whole vulva, but it can also be limited to a certain part or unilateral vulva. Although itching is very serious and even unbearable, the appearance of local skin and mucosa is normal, or there are only scratches and blood scabs caused by excessive scratching. When making a diagnosis, we should inquire about the course of disease in detail, carefully carry out local and general examinations and necessary laboratory examinations, and try our best to find out the cause.
