title: Acquired cutis laxa associated with heavy chain deposition disease.
abstract: Acquired cutis laxa (generalized acquired elastolysis) is a condition of unknown etiology characterized by a degeneration of elastic fibers in the skin, resulting in laxity with reduced elastic recoil. We describe a patient with acquired cutis laxa associated with an underlying heavy chain deposition disease. Direct immunofluorescence testing of lesional skin demonstrated immunoglobulin G deposition on elastic fibers, suggesting that in some cases, cutis laxa may have an immune-mediated etiopathogenesis.
