Cutis rhomboidalis nuchae

Synopsis

Cutis rhomboidalis nuchae (CRN) is a common clinical variant of solar elastosis in which the skin of the posterior neck becomes thickened, leathery, and deeply furrowed in a geometric pattern. The condition is a marker of chronic sun damage with the subsequent development of disorganized and damaged collagen and elastic tissue.

CRN primarily affects elderly men and women with lighter skin phototypes and history of significant sun exposure. Outdoor occupations also predispose patients to CRN.

CRN is a chronic condition, and once the skin changes have occurred, it is difficult, if not impossible, to reverse the appearance of the skin.
