We describe two patients with pregnancy-associated pigmentary demarcation lines overlapped by erythematous changes. In both cases, there was a symmetrical well-defined erythematous pigmentation involving the buttocks and flexor aspects of the legs. After normal delivery the erythema disappeared within 7-10 days, followed by slow resolution of the pigmentation. Compression by the enlarged uterus of peripheral nerves issuing at S1-S2 is proposed as a mechanism of these changes.
我们描述了两名患有妊娠相关色素沉着分界线且伴有红斑改变的患者。在这两个病例中，均出现了累及臀部和腿部屈侧的对称性边界清晰的红斑色素沉着。正常分娩后，红斑在7 - 10天内消失，随后色素沉着逐渐消退。推测这些改变的机制是S1 - S2发出的周围神经受到增大子宫的压迫。
