Anetoderma

The term "anetoderma" originates from the Greek words (relaxed) and (skin). First described by Jadassohn in 1892, anetoderma is a benign disorder of elastolysis characterized by well-circumscribed, focal areas of flaccid skin. Clinically, these lesions appear as round to oval atrophic depressions, wrinkled macules, patches, or herniated sac-like protrusions surrounded by normal skin. The lesions may be skin-colored, white, gray, brown, or blue and can measure from millimeters to centimeters. Anetoderma most commonly affects the trunk and proximal extremities. Once present, the disease remains active for at least 15 years. Spontaneous regression has never been reported.
