Vulvar dystrophy is the abnormal growth of the skin of the vulva, in a benign but symptom-provoking manner.

There are two forms of vulvar dystrophy:
- Lichen sclerosus, in which the skin of the vulva is too thin, and
- Hypertrophic vulvar dystrophy, in which the skin of the vulva is growing too thick.
- A third form, mixed dystrophy, is a combination of both.

Both forms are associated with vulvar itching (pruritus) and burning, not responsive to anti-fungals, antibiotics or other creams or salves. Both can cause a white discoloration of the skin.

While very experienced examiners may be able to predict which form of vulvar dystrophy is present in a patient, based on observation alone, a vulvar biopsy is usually needed to confirm the diagnosis.
