Crescentic/necrotizing GN in 60 yo man with RPGN, positive anti-MPO. No glomerular hypercellularity or capillary wall thickening, but surprisingly 3+diffuse granular GBM staining with IgG by IF. Now need to rule out SLE and order PLA2R serology #renalpathology

Multiple interlobular arteries showing fibrinoid necrotizing arteritis in a man in 70s with ANCA-associated vasculitis. Necrotizing crescentic GN also present (not shown) #renalpathology

Today I had the priviledge to host dr Astrid Weins and dr Sanjeev Sethi in my department! What an honour! #universityhospitalcenterzagreb #nephrology #renalpathology

50 yo M with nephrotic syndrome. Tip lesion by LM, but finely granular IF staining of GBM. Many subepithelial deposits by EM. Actually a case of PLA2R- associated membranous nephropathy #renalpathology #fsgsisapatternofdisease

Graft biopsy from 40s yo man s/p tx 6+ y shows tubular nuclei with intranuclear viral inclusions. SV40 positive. No BK viremia detected #JCvirus #renalpathology

Great week sharing the art of #renalpathology with Chuan Chen, MD PhD .
A bx of a young woman with hematuria & proteinuria. Routine IF had ZERO glomeruli. But a salvage IF technique clinches the suspected dx.
