Sores or lesions on the female genitalia or in the vagina may have a number of possible causes.
Sores or lesions on the female genitalia are often caused by sexually transmitted infections (STIs).
STIs that cause visible and fairly classic-appearing lesions include:
Genital sores may be painful, itchy, produce a discharge, or cause no symptoms at all.
Precancerous changes of the vulva (vulvar dysplasia) may appear as white, red, or brown patches on the vulva, and may cause itching. The vulva can also develop skin cancers such as melanoma and basal cell and squamous cell carcinomas.
Non-sexually transmitted diseases may also produce lesions on the genitalia. In young girls (before puberty), nonspecific vulvovaginitis, atopic dermatitis, and contact dermatitis are common causes of genital lesions. Less common causes include lichen planus, lichen sclerosis, seborrheic dermatitis, and vitiligo. Benign cysts or abscesses of the Bartholin's or Skene's glands can cause pain or swelling in areas of the vulva.
Rarely, a medical illness, such as Crohn's disease, can cause genital lesions.
Because genital lesions or sores often adversely affect a person's self-image, many individuals do not seek proper medical care. All genital sores should be evaluated by a medical professional.
Itching, painful urination, or painful sexual intercourse often accompany genital lesions.
Avoid self-treatment before seeing a doctor. It can mask the symptoms and make diagnosis of the cause of the sore more difficult.
A sitz bath may be recommended to relieve itching and crusting. Moist lesions can be dried by using a heat lamp.
If the sores are caused by a sexually transmitted infection, the sexual partner should be notified and treated, and all sexual activity should be discontinued until the lesions are no longer infectious.
Your doctor will perform a physical examination and ask medical questions to identify:
- Type of lesion
- What color is the lesion?
- How big is it?
- Is it painful?
- Does it itch?
- Is it scaly?
- Does the border look distinct (sharp) or blurry?
- Time pattern
- When did you first notice the lesion?
- Have you ever had a similar lesion in the past?
- Distribution
- Has the lesion grown larger?
- Is there an increasing number of lesions?
- How many lesions are there?
- Where on the genitals is the lesion located?
- Other
The physical examination will usually include a pelvic examination.
The following tests may be done:
Treatment may include medications that are applied to the skin or that are taken by mouth. The type of medication depends on the cause, but may include corticosteroids, antiviral drugs, antibiotics, or drugs to control itching.
