Fibrillary glomerulonephritis (FGN) is a rare form of glomerulonephritis, usually occurring in concurrence with other conditions such as hepatitis C, dysproteinemia, autoimmune conditions, diabetes mellitus, and malignancy. The diagnosis is made by the presence of randomly oriented fibrillar deposits with a mean diameter of 20 nm, which stain positive for IgG and C3 and are negative for congo red and thioflavin T stains. Staining for DNAJB9 (DnaJ homolog subfamily B member 9) is a recently discovered mode of diagnosis of FGN without electron microscopy. The prognosis is poor and optimal treatment is yet not clearly defined, though rituximab may be useful in FGN patients with relatively preserved renal functions. In this case report, we discuss a case of post-renal transplant patient with de novo occurrence of fibrillary glomerulonephritis.
