ANSWER: B.Decoy cells are epithelial cells containing intranuclear viral inclusions in urine. They are not specific for polyomavirus nephritis, but when present they may indicate polyoma infection of urinary tract. Decoy cells are easily identified in routine Papanicolaou stained.
#PathQuiz While this cell type is not specific for polyomavirus nephritis, when found in the urine it can indicate polyoma infection of urinary tract. What is the name of this type of cell? #pathology #pathX #renal #renalpath.

The immunofluorescence image is that of an Alport panel. The red staining highlights the alpha 2 subunit of collagen type IV while the green staining is that of the alpha 5 subunit of collagen type IV. The image shows segmental loss of the alpha 5 staining of type IV collagen.

This biopsy from a patient with massive proteinuria showed diffuse and near-global involvement of glomeruli by amorphous deposits (Fig. 1) which were Congo red positive (not shown). The amyloid subtype was confirmed as AA amyloid using immunohistochemistry (Fig. 2).

ANSWER: B.The findings are suspicious for active antibody mediated rejection (ABMR), based on presence of moderate glomerulitis (g2), severe peritubular capillaritis (ptc3) and C4d staining in PTCs (C4d2). Serologic evidence of DSA is advised in order to meet the criteria for.
#PathQuiz A renal biopsy from a young patient, s/p transplant 1 year ago, showed interstitial edema and inflammation with moderate glomerulitis and severe peritubular capillaritis. No vasculitis seen. IF showed positive C4d along 50% of the PTCs. Which would be the suspected.
