Mid-dermal elastolysis.

Mid-dermal elastolysis (MDE), which presents as fine wrinkling of the skin or perifollicular papules, is extremely rare. This entity is distinguished from other elastolytic disorders by its characteristic bandlike loss of elastic fibers limited to the mid dermis. We report a case of MDE that developed gradually in an otherwise healthy woman without prior cutaneous disease. The current theories on the pathogenesis of MDE also are discussed.
