妊娠性多形疹

定义

妊娠多形疹是一种几乎只发生在初产妇或多胎妊娠妇女身上的皮炎。它与妊娠期体重增加高于平均水平有关，腹部皮肤扩张在发病机制中很重要：确切机制尚不清楚。典型皮疹最早出现在妊娠晚期，表现为腹部妊娠纹及其周围出现瘙痒难耐的红斑性荨麻疹性丘疹及斑块。在一些妇女中，它可能会变得更加普遍。发病时间有时会推迟到产后不久。在以后的妊娠中通常不复发。

Polymorphic eruption of pregnancy is a dermatosis which occurs almost exclusively in primigravidae or women with multiple pregnancy. It is associated with above average weight gain in pregnancy and it is thought that distension of abdominal skin is important in the pathogenesis: the precise mechanism is not understood. The eruption characteristically first appears in the third trimester of pregnancy as intensely itchy erythematous urticarial papules and plaques in and around the abdominal striae distensae. In some women it may then become more generalised. Onset is sometimes delayed until the immediate postpartum period. It does not usually recur in subsequent pregnancies.
