Pseudoxanthoma elasticum (PXE) is a rare, inherited, multisystem disorder characterized by progressive calcification and fragmentation of elastic fibers. Typically, small, yellowish papules are located on the neck and flexural areas; however, localized acquired cutaneous PXE has been proposed as a non-heritable form of the disorder. We report a patient who had normal appearing skin on the chin with an itching sensation and had PXE-like changes by skin biopsy.
