Anetoderma is a localized laxity of the skin with herniation or outpouching resulting from abnormal dermal elastic tissue. Anetoderma comes in three types: * Primary anetoderma * Jadassohn–Pellizzari anetoderma is a benign condition with focal loss of dermal elastic tissue. Jadassohn-Pellizzari is one of two major classifications of primary anetoderma, the other being Schweninger–Buzzi anetoderma. The difference between the two is that Jadassohn–Pellizzari anetoderma is preceded by inflammatory lesions. * Schweninger–Buzzi anetoderma is a cutaneous condition characterized by loss of dermal elastic tissue. * Secondary anetoderma * Familial anetoderma
