{Reference Type}: Case Reports {Title}: A Rare Case of Diabetic Nephropathy and Type III Collagen Glomerulopathy. {Author}: Toro D;Khan R;Mohammed A; {Journal}: Cureus {Volume}: 15 {Issue}: 8 {Year}: 2023 Aug 暂无{DOI}: 10.7759/cureus.44284 {Abstract}: Collagenofibrotic glomerulopathy (CG) is a poorly understood kidney disease characterized by extensive deposition of abnormal type III collagen within the glomeruli. We report the case of a 25-year-old man with known type I diabetes mellitus who presented to the emergency department with diaphoresis, nephrotic-range proteinuria, hypertension, and elevated creatinine. Renal biopsy revealed combined collagenofibrotic glomerulopathy and diabetic nephropathy. This case highlights the clinicopathological features of type III collagen glomerulopathy and its possible association with diabetic nephropathy.
