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.

Background: Autosomal recessive cutis laxa type 1B (ARCL1B) is an extremely rare disease characterized by severe systemic connective tissue abnormalities, including cutis laxa, aneurysm and fragility of blood vessels, birth fractures and emphysema. The severity of this disease ranges from perinatal death to manifestations compatible with survival. To date, no cases have been reported in the Chinese population.

The surgical principles of treating a high riding hip dislocation in patients with positive PYCR1 gene mutation should be comprehensive including open reduction, pelvic osteotomy, and femoral shortening osteotomy with derotation. Meticulous capsulorrhaphy optimizes the development and stability of the hip joint.

Loss-of-function variants in ATP6V0A2, encoding the trans Golgi V-ATPase subunit V0a2, cause wrinkly skin syndrome (WSS), a connective tissue disorder with glycosylation defects and aberrant cortical neuron migration. We used knock-out (Atp6v0a2) and knock-in (Atp6v0a2) mice harboring the R755Q missense mutation selectively abolishing V0a2-mediated proton transport to investigate the WSS pathomechanism. Homozygous mutants from both strains displayed a reduction of growth, dermis thickness, and elastic fiber formation compatible with WSS.
