Pigmentary demarcation lines (PDL), or Voigt-Futcher lines, are lines that mark an abrupt transition between hyperpigmented skin and normal skin. PDLs are more common in Japanese and dark-skinned individuals. Eight types have been described (A-H); Type B is located on the posteromedial aspect of the lower extremities; it is more common in women and is the one most frequently associated with pregnancy. The demarcation lines of pregnancy are of unknown etiology; they appear mainly in the last trimester and disappear spontaneously months after delivery. We report a case of pregnancy-associated PDL with erythema without melanocytic pigmentation in a 23-week-gestational Latin primiparous woman.
色素分界线（PDL），即沃伊特 - 富彻线，是标志着色素沉着皮肤与正常皮肤之间突然转变的线条。色素分界线在日本人和深色皮肤个体中更为常见。已描述了八种类型（A - H）；B型位于下肢的后内侧；在女性中更常见，并且是最常与妊娠相关的类型。妊娠分界线的病因不明；它们主要出现在妊娠晚期，并在分娩后数月自发消失。我们报告了一例妊娠相关的色素分界线病例，该病例发生在一名妊娠23周的拉丁裔初产妇身上，伴有红斑但无黑素细胞色素沉着。
