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.
        
        
 
        
	
            
            Implication for health policy/practice/research/medical education:
  The coexistence of CN and MN is a rare finding. This case highlights its difficult management and the potential benefit of rituximab  administration in this rare entity of kidney disease.
