Collapsing glomerulopathy is common in the setting of thrombotic microangiopathy of the native kidney.

Thrombotic microangiopathy (TMA) is a poorly recognized cause of collapsing glomerulopathy. The frequency and significance of collapsing glomerulopathy associated with renal TMA have not been specifically studied in native kidney biopsy specimens. Here we retrospectively documented clinicopathologic features of 53 patients with histologically proven TMA in the native kidney, with special emphasis on changes due to focal segmental glomerulosclerosis (FSGS).

Renal Cortical Necrosis in Postpartum Hemorrhage: A Case Series.

Background: Pregnancy-related renal cortical necrosis may lead to end-stage renal disease. Although this obstetric complication had virtually disappeared in high-income countries, we have noted new cases in France over the past few years, all following postpartum hemorrhage.

Study Design: Case series.
