Membranous nephropathy (MN) or membranous glomerulonephritis (MGN) is a common glomerulonephritis that usually presents with nephrotic-range proteinuria, edema, and hypertension.  MN is generally classified as primary (idiopathic) or secondary to other systemic disease, such as infections, malignancies, vasculitides etc. Primary MN has been recently associated with a newly discovered phospholipase A2 receptor (PLA2R) nephrotigenic antigen on the membrane surface of glomerular podocytes and the presence of anti-PLA2R antibodies. Kidney biopsy remains the gold standard for the diagnosis of MN, showing subepithelial deposits with capillary wall thickening and IgG deposition under immunofluorescence. While MN is widely considered a chronic condition with a waxing and waning course, it is usually self-limited in the majority of the cases. Heavy proteinuria, a significant marker of prognosis, indicates the need for intervention.
