Placental findings in pregnancy-associated haemolytic uremic syndrome: clinicomorphological study of three cases.

Acute renal failure occurring in pregnancy or postpartum is often associated with preeclampsia, HELLP syndrome or haemolytic uremic syndrome: differential diagnosis may be difficult due to the overlapping symptoms of these syndromes. We report our experience on diagnosis, management and outcome of women with pregnancy associated haemolytic uremic syndrome, focusing on placental features.
