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 PLA2R-associated MN with collapse, its treatment and clinical course.
