PVN is a well‐known cause of renal allograft dysfunction and failure. The diagnosis is established by examination of tissue from the renal graft, and confirmed by immunohistochemical or in situ hybridization techniques. Electron microscopy can be utilized as an ancillary modality to identify the viral particles ultrastructurally. The tubular epithelial cells are the primary target of PV cytopathic effect; however, PV ‐associated glomerular changes have also been described. Immune‐type electron‐dense deposits in the TBMs have been described in the setting of PVN , and rarely, likewise have glomerular subepithelial hump‐like deposits. Diffuse immune‐mediated proliferative glomerulonephritis in the setting of PVN has not been reported before. In this report, we describe an 11‐yr‐old kidney transplant recipient boy who developed immune‐mediated glomerulonephritis with light microscopic, immunofluorescence, and ultrastructural features compatible with acute PIGN superimposing chronic PVN , discuss this unusual association and the possible mechanisms of antigen clearance in PVN and present a literature review.
