Common Infectious Causes of Pruritus Vulvae
Pruritus vulvae, or vulvar itching, is most often caused by infections, especially in sexually active women. The most common infectious cause is vulvovaginal candidiasis, a yeast infection. Changes in the normal bacterial flora of the vulva can also lead to itching and burning sensations. Other infectious agents, such as bacteria and parasites (like pinworms in children), can also be responsible, though these are less common. In older women, the risk of bacterial infections increases due to changes in vaginal pH and flora after menopause Strunin1973Woelber2020Kaur2017+3 MORE.
Non-Infectious Dermatological Causes
Non-infectious skin conditions are another major group of causes. Chronic dermatoses such as lichen sclerosus, lichen planus, lichen simplex chronicus, and eczema are frequently identified. Lichen sclerosus is particularly common and can affect women of all ages, including young girls and postmenopausal women. Contact dermatitis, often from soaps or hygiene products, is also a frequent trigger, especially in children and those with sensitive skin Strunin1973Woelber2020Kaur2017+5 MORE.
Age-Related and Hormonal Factors
In the geriatric population, hormonal changes after menopause lead to thinning, dryness, and loss of elasticity in vulvar skin, making it more prone to itching. Atrophic vaginitis, a result of decreased estrogen, is a common diagnosis in older women. These changes also make the vulva more susceptible to infections and other irritants Kaur2017Bohl2005.
Rare and Unusual Causes
Although less common, pruritus vulvae can be caused by neoplastic conditions such as vulvar intraepithelial neoplasia or even malignancy, especially in cases that do not respond to standard treatments. Rarely, benign tumors like syringomas can present with vulvar itching, and these should be considered when papular lesions are present Woelber2020Freeman2023Bohl2005+2 MORE.
Pediatric Considerations
In prepubertal girls, most cases of pruritus vulvae are nonspecific and often related to poor hygiene or irritant exposure, such as soaps. However, lichen sclerosus, bacterial and yeast infections, and pinworm infestations are also possible causes in this age group. Improved hygiene and avoidance of irritants often resolve symptoms in children Bohl2005Paek2001.
Importance of Accurate Diagnosis
Because pruritus vulvae has a wide range of possible causes, a thorough history and examination are essential for effective management. In some cases, further investigations such as skin biopsy or referral to a specialist may be needed, especially if malignancy is suspected or if symptoms are resistant to treatment. Treatment should be tailored to the specific cause, and general measures to reduce irritation and improve vulvar care are recommended for all patients Woelber2020Freeman2023Thoroughgood2012+1 MORE.
Conclusion
Pruritus vulvae is a common symptom with diverse causes, including infections, chronic skin conditions, hormonal changes, irritants, and, rarely, tumors or malignancy. Accurate diagnosis is crucial for effective treatment and to address the underlying cause, especially in persistent or unusual cases.
