Light microscopy of the renal lesion of preeclampsia: glomerular endotheliosis. On light microscopy, the glomeruli from preeclamptic women are characterized by swelling of the endothelial and mesangial cells. This swelling results in obliteration of the capillary lumina, giving the appearance of a bloodless glomerulus. On occasion, the mesangium, severely affected, may expand. Thrombosis and fibrinlike material and foam cells may be present, and epithelial crescents have been described in rare instances [2].
