What is the disease caused by extreme itching of the vulva and leucorrhea that looks like tofu?

Itching of the vulva and leucorrhea that looks like tofu are usually typical manifestations of vulvovaginal candidiasis.

1. Vulvovaginal candidiasis

Vulvovaginal candidiasis is a common gynecological disease caused by Candida yeast infection. The main symptoms include severe itching and burning of the vulva, increased leucorrhea, and a tofu-like or curd-like appearance. Common causes of the disease include long-term use of antibiotics, pregnancy, poorly controlled diabetes, and low immunity. Typical symptoms are congestion and edema of the vulvar mucosa, with white film attached to the surface, and erosion can be seen after erasure. Confirmation requires microscopic examination of vaginal secretions to detect Candida spores and pseudohyphae.

2. Bacterial vaginosis

Although bacterial vaginosis mainly manifests as gray-white thin leucorrhea with a fishy odor, some patients may be complicated by Candida infection, causing vulvar itching and tofu-like leucorrhea. It is characterized by the reduction of normal lactobacilli in the vagina and the excessive reproduction of anaerobic bacteria, resulting in vaginal microecological imbalance. Diagnosis is based on a positive amine test, detection of clue cells, and vaginal pH greater than 4.5.

3. Trichomonal vaginitis

Trichomonal vaginitis usually presents as yellow-green foamy leucorrhea with obvious odor. However, in severe cases, it may irritate the vulvar skin and cause severe itching. At the same time, abnormal leucorrhea may appear when combined with other pathogenic infections. Trichomonas vaginalis can be transmitted through sexual contact, and patients often experience urinary discomfort and dyspareunia. Wet film examination shows active trichomonas is the basis for diagnosis.

4. Allergic vulvitis

Allergic vulvitis may cause severe itching of the vulva due to allergies to sanitary products, drugs or clothing materials. Repeated scratching may cause secondary infection and abnormal leucorrhea. The main clinical manifestations are vulva redness, swelling, papules, and erosion, and the symptoms are closely related to exposure to allergens. It is necessary to inquire about the contact history in detail and conduct a patch test if necessary to identify the allergen.

5. White spots on vulva

Vulvar leukoplakia, also known as vulvar lichen sclerosus, is a chronic vulvar dystrophic disease, mainly characterized by intractable itching of the vulva, skin depigmentation and atrophy. In severe cases, scratching may lead to skin damage and secondary infection, resulting in changes in the characteristics of leucorrhea. The disease needs to be confirmed through pathological biopsy. Those who do not heal for a long time are at risk of malignant transformation and need regular follow-up.

When you experience vulvar itching and tofu-like leucorrhea, it is recommended to wear cotton breathable underwear, avoid using irritating lotions to clean the vulva, and keep the vulva clean and dry. It is forbidden to use vaginal douches by yourself to avoid damaging the balance of vaginal microenvironment. Sexual intercourse should be avoided during treatment, and sexual partners should be treated simultaneously to prevent cross-infection. Diabetic patients need to strictly control their blood sugar, and those who use antibiotics for a long time should adjust their medication regimen under the guidance of a doctor. If symptoms recur or are accompanied by fever, pelvic pain, etc., you should seek medical treatment in time to rule out other gynecological diseases.
