Moderately developed tubulitis was noted in the middle of the field (PAS, ×200). (b–d) Negative staining of SV40 (b), EBER (c), and IgG4 (d) in allograft specimen (×200). (e) CD138-positive interstitial inflammatory cells (×200). (f, g) Infiltrating plasma cells positive for both kappa (f) and lambda (g) light chains, indicating that they are polyclonal (×200).
