The vulva is the area outside the opening of the birth canal. This area can develop white spots of thick or thin skin called dystrophies.
Dystrophies are all harmless.
They do not grow in size or develop into cancer. A healthcare provider can help if you think you have a white area. Sometimes a sample of the skin called a biopsy will be needed to make sure of this diagnosis. In general, the thickened type is a result of irritation. You can be any age when this develops, although it occurs most commonly in older women.
