Leukoplakia of the vulva

Leukoplakia is a chronic condition characterized by the formation of whitish patches (plaques) on the mucous membrane of the vulva. These changes are associated with hyperkeratosis—excessive thickening of the outermost epithelial layer. Vulvar leukoplakia is considered a precancerous condition, as in some cases it may progress to malignant tumors; however, the overall risk of malignant transformation is relatively low. Vulvar leukoplakia most commonly occurs in women aged 50 years and older, particularly in the postmenopausal period.

Causes of leukoplakia

1. Hormonal changes. Leukoplakia often develops in postmenopausal women due to decreased estrogen levels, leading to atrophy (thinning) of the mucous membranes.
2. Mechanical irritation. Friction from clothing, frequent use of hygiene products, or sexual activity may cause chronic irritation of the vulvar skin and mucosa, contributing to the development of leukoplakia.
3. Infectious diseases. Chronic inflammatory processes caused by infections (viral, bacterial, or fungal) may result in epithelial structural changes.
4. Immune disorders. Weakened immunity or autoimmune diseases may also play a role in the development of leukoplakia.
5. Chronic inflammation. Persistent inflammatory conditions in the genital area (vulvitis, vaginitis) can promote mucosal alterations.
6. In some women, a genetic predisposition to vulvar leukoplakia may be present.

Symptoms of vulvar leukoplakia

• Itching and burning. Patients often experience itching, burning, or discomfort in the genital area, especially with friction or contact with underwear.
• Dryness of the skin. The vulvar skin and mucosa may become dry and rough, increasing the risk of fissures.
• Pain during sexual intercourse. Due to dryness and altered tissue structure, sexual intercourse may become painful.
• Changes in skin appearance. Lesions may appear white or gray and may be slightly elevated above the skin surface. In rare cases, cracks or ulcerations may develop.

Diagnosis of leukoplakia

1. Gynecological examination. The physician visually examines the vulvar mucosa for whitish lesions and other abnormalities.
2. Colposcopy. Examination of the mucosa under magnification using a colposcope allows detailed assessment of affected areas and detection of pathological tissue changes.
3. Biopsy. To confirm the diagnosis and exclude malignant transformation, a tissue sample may be taken from the affected area for histological examination.
4. Cytological examination. A smear may be obtained to evaluate the cellular composition and identify signs of dysplasia (precancerous changes).

Treatment of vulvar leukoplakia

Medical treatment: hormonal therapy; anti-inflammatory medications; antiseptic and wound-healing agents.

Surgical treatment: laser therapy; electrocoagulation; cryodestruction.

Lifestyle modification and skin care

• Regular and gentle intimate hygiene helps prevent inflammation and irritation. Aggressive cleansing agents should be avoided.
• Supporting the immune system through balanced nutrition and avoidance of harmful habits may improve mucosal health.
• Loose, breathable underwear made of natural fabrics is recommended to reduce friction and irritation.

Prognosis and prevention

With timely diagnosis and appropriate treatment, the prognosis for vulvar leukoplakia is generally favorable, especially when detected at early stages. However, as leukoplakia is a precancerous condition, regular medical follow-up is essential to exclude potential malignant transformation.

Prevention includes:

• Regular gynecological examinations and follow-up.
• Maintenance of hormonal balance, particularly during the postmenopausal period.
• Proper intimate hygiene using mild, hypoallergenic products.
• Adherence to a healthy lifestyle, including avoidance of smoking and alcohol.

Vulvar leukoplakia is a chronic condition that requires medical attention and treatment, particularly due to the risk of malignant transformation. Modern diagnostic and therapeutic approaches allow effective management of this condition, improvement of quality of life, and prevention of complications. Regular gynecological check-ups and adherence to medical recommendations are essential for early detection and timely treatment.
