Cutis laxa type II and wrinkly skin syndrome: distinct phenotypes.

Cutis laxa is a heterogeneous group of disorders with variable phenotypes and inheritance patterns. Type II cutis laxa has features overlapping with wrinkly skin syndrome, as a result of which they are regarded as one disorder with a variable spectrum of severity by some authors. To overcome this existing confusion, we present three patients with cutis laxa type II and review the literature to highlight the important differentiating features between cutis laxa type II and wrinkly skin syndrome.
