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.
弹性假黄瘤(PXE)是一种罕见的遗传性多系统疾病,其特征为弹性纤维进行性钙化和断裂。通常,颈部和屈侧部位会出现小的淡黄色丘疹;然而,局限性获得性皮肤弹性假黄瘤已被认为是该疾病的一种非遗传性形式。我们报告了一名患者,其下巴处皮肤外观正常,但有瘙痒感,经皮肤活检显示有弹性假黄瘤样改变。
