Eight cases with striae distensae associated with obesity or prolonged corticosteroid intake were examined by light and scanning electron microscopy. Fine elastic fibers predominated in early lesions, while thick elastic fibers predominated in older lesions. In early lesions the periphery showed thick and tortuous elastic fibers, but in older lesions it was of normal appearance. It is suggested the elastic fibers in striae were newly synthesized and gradually increased and thickened with age.
对8例与肥胖或长期服用皮质类固醇有关的膨胀纹患者进行了光镜和扫描电镜检查。早期病变中以细弹性纤维为主，而陈旧性病变中以粗弹性纤维为主。早期病变的周边可见粗而扭曲的弹性纤维，而陈旧性病变的周边外观正常。提示膨胀纹中的弹性纤维是新合成的，并随年龄增长而逐渐增多、增粗。
