A membranous pattern is occasionally present in Fibrillary GN Notice randomly arranged fibrils in the subepithelial regions. DNAJB9-positivity is seen in a similar distribution by IHC. Can be mistaken for membranous nephropathy: doi.org/10.1016/j.ekir…. #renalpath #PathTwitter

Membranous nephropathy (MN) antigens from a single center in Portugal. Starting point=negative serum anti-PLA2R titer cases. We detected MN antigens: 3 PLA2R, 2 NELL1, & 1 each EXT1/EXT2, HTRA1, THSD7A. Antigens correlated with underlying disease. 1/2 kireports.org/article/S2468-…

This FSGS was scarier than any crescent…fierce looking, activated podocytes as if ready to engulf the tuft.. And look at the tuft-scared to the core.. 🥹😱 #CollapsingFsgs #RenalPath #PathTwitter #Nephtwitter #RenalPathSociety #AskRenal #RenalPathLabsGurugram #KidneyBiopsy

Kidney bx for RPGN. MPO ANCA +++ Temporal heterogeneity of crescents seen. Fibrinogen highlights a crescent (grey arrow). IgG shows trace to 1+ deposits in glomerulus. Remember its PAUCI immune crescentic GN - we can have “some” immune deposits!! What do you think?
