A 36-year-old woman presented with a 20-year history of light flat papules on the trunk and limbs. The lesions developed slowly and were asymptomatic. Skin examination revealed multiple irregularly sized light flat papules on the trunk and limbs along Langer's lines,multiple pin cap-sized perifollicular papules on the posterior upper arm. Part of papules merged into plaques. Pathological examination of biopsy showed epidermal atrophy and thinning,and thinned collagen fibers arranged loosely in the dermis. Alcian blue staining revealed no mucoprotein in the dermis. Verhoeff-van Giesen's Staining showed almost complete absence of elastic fibers in the mid dermis. Based on the above findings,the diagnosis was made as mid-dermal elastolysis.
