An atrophic disease affecting the female external genitalia, most often of older women, resulting in drying and shriveling of the parts, and marked by leukoplakic patches on the mucosa, itching, dyspareunia, dysuria, and soreness. It occurs most commonly as a result of lichen sclerosus et atrophicus of the vulva, but may be associated with other types of genital atrophy. (Dorland, 27th ed)
