Simultaneous membranous nephropathy and diabetic nephropathy occurrence in a patient: A case report

Abstract Membranous nephropathy (MN) is the most common glomerular disease in adults and is constantly associated with the occurrence of nephrotic syndrome. While diabetic kidney disease (DKD) and diabetic nephropathy (DN), which often occur in diabetic patients, are considered as the major causes of end-stage kidney disease. Actually, MN often occurs in patients with diabetes mellitus (DM), but to obtain a clear differential diagnosis without a renal biopsy has become difficult. Here we report the case of a female diabetic patient who developed both MN and DN simultaneously.
