Abstract

Background

Bile staining in the hepatobiliary tree is a well-known phenomenon, but bilirubin can also be deposited in and stain the umbilical cord, amniotic fluid, placental disk and placental membranes.

Case Report

We present a placenta with grossly greenish discoloration of the placental disk and microscopic villous bilirubin deposition due to maternal hyperbilirubinemia. Conclusion: Maternal hyperbilirubinemia causes massive bilirubin deposition in villous synctiotrophoblasts and Hofbauer cells leading to grossly green discoloration of the placental disk.

绿色胎盘：母体高胆红素血症引起的大量胎盘胆红素沉积

摘要

背景

肝胆树中的胆汁染色是众所周知的现象，但胆红素也可沉积并染色于脐带、羊水、胎盘和胎盘膜。

案例报告

我们展示了一个胎盘，由于母体高胆红素血症，胎盘盘明显呈绿色变色，显微镜下可见绒毛状胆红素沉积。结论：母体高胆红素血症导致绒毛合体滋养细胞和霍夫鲍尔细胞中大量胆红素沉积，导致胎盘显着变绿。
