Unilateral dermatomal superficial telangiectasia (UDST) may be congenital or acquired. Acquired UDST may occur coincident with physiologic states of estrogen increase, including puberty and pregnancy in women and adrenarche in men. Acquired UDST may also occur in estrogenized pathologic states such as chronic hepatic disease in alcoholism. The occurrence during estrogenized states, the dermatomes of distribution, and the presence of anemic halos suggest kinship with arterial spiders. UDST and some cases of benign, generalized telangiectasia may be local and universal forms, respectively, of the same pathologic process in the cutaneous microvasculature. Further, this is compatible with both the concept that UDST results from a somatic mutation and the usual nonfamilial presentation of UDST.
单侧皮节性浅表毛细血管扩张（UDST）可能是先天性的，也可能是后天获得性的。后天获得性UDST可能与雌激素水平升高的生理状态同时出现，包括女性的青春期和妊娠以及男性的肾上腺初现。后天获得性UDST也可能出现在雌激素化的病理状态下，如酒精性慢性肝病。在雌激素化状态下的出现、分布的皮节以及贫血晕的存在提示与蜘蛛痣有关。UDST和一些良性全身性毛细血管扩张病例可能分别是皮肤微血管同一病理过程的局部和普遍形式。此外，这与UDST由体细胞突变引起的概念以及UDST通常的非家族性表现均相符。
