Membranous nephropathy with collapse in a HIV negative patient; a case report with a 34-month follow-up

Abstract

Membranous nephropathy (MN) is a common cause of nephrotic syndrome (NS) in nondiabetic adults. Collapsing nephropathy (CN) is a morphological pattern that is usually classified as a variant of focal segmental glomerulosclerosis (cFSGS). The simultaneous presence of both MN and CN is rare and their combination usually foresees an unfavorable outcome. Herein, we describe a case report of a patient with PLA2 R-associated MN with collapse, its treatment and clinical course.
