Anetoderma is a benign disorder of elastolysis, causing well-circumscribed, focal areas of flaccid skin. The localized areas of slack skin can present clinically as round to oval atrophic depressions, wrinkled macules, patches, or herniated sac-like protrusions with a surrounding border of normal skin. The lesions can be a variety of colors from skin-colored, white, grey, brown, or blue, and the size can range from millimeters to centimeters. Anetoderma most commonly presents on the trunk and proximal extremities. Once present, the disease tends to be active for at least 15 years. No reports of spontaneous regression have occurred.
