Short answer · Medically reviewed summary · Last updated: 2026-05-08
Cutis laxa is a rare group of connective tissue disorders characterized by inelastic, redundant, and sagging skin, first formally described in the medical literature in the 18th century. Over time, our understanding of cutis laxa has shifted from a purely dermatological observation to a complex genetic reality involving mutations in genes responsible for elastin synthesis and extracellular matrix integrity. When was cutis laxa first described? The first documented accounts of cutis laxa date back to the 1700s, often appearing in medical texts as "dermatolysis." Early physicians were fascinated by the clinical presentation of skin that lacked recoil, often documenting these cases in traveling circuses or anatomical theaters.

The first documented accounts of cutis laxa date back to the 1700s, often appearing in medical texts as "dermatolysis." Early physicians were fascinated by the clinical presentation of skin that lacked recoil, often documenting these cases in traveling circuses or anatomical theaters. It was not until the 20th century that clinicians began to differentiate cutis laxa from other connective tissue disorders, such as Ehlers-Danlos syndrome, by observing the specific loss of elastic fibers rather than just collagen abnormalities.
Historically, cutis laxa was misunderstood as a purely cosmetic skin condition. However, researchers eventually identified that the condition is systemic, frequently affecting the lungs (emphysema), the heart (aortic aneurysms), and the gastrointestinal tract. The evolution of molecular genetics in the late 20th and early 21st centuries allowed scientists to identify specific causative genes, such as ELN, FBLN5, and ATP6V0A2, which finally provided a biological explanation for the diverse clinical manifestations of cutis laxa.
