title: Localized acquired cutaneous pseudoxanthoma elasticum.
abstract: Localized acquired cutaneous pseudoxanthoma elasticum is a new designation proposed for a nonheritable form of pseudoxanthoma elasticum (PXE), lacking the retinal and vascular stigmata associated with the inherited form of the disorder, but having skin lesions that are clinically, histologically, and ultrastructurally similar to those seen in the inherited type. A patient is presented with skin lesions confined to the chest and abdomen. Similar cases from the literature, some apparently idiopathic in multiparous black females and others with histories of cutaneous exposures to calcium salts, are grouped together as examples of the acquired form of PXE.
