Vulvar dystrophy is a change in the skin of the
vulva, the outer part of a female’s genitals. The area becomes dry, with
white or grey patches, and the skin of the vulva becomes either too thick or too thin. Symptoms include extreme burning and itching. This is a progressive condition which can lead to narrowing of the vaginal and rectal openings if left untreated. Hence timely treatment is necessary. Hope this helps.
Take care and good luck.
