Fig. 1From: The pathological features of leukemic cells infiltrating the renal interstitium in chronic lymphocytic leukemia/small lymphocytic lymphoma from a large single Chinese centerRepresentative light microscopic findings of renal biopsy. A. CLL cells infiltration was seen in the renal interstitium (HE, ×200). B. Vaguely nodular pattern was seen in the renal interstitium(HE, × 630). C. Interstitial epithelioid granulomas were formed in the renal interstitium as indicated by the arrow (HE, × 200). D. Infiltrating CLL cells stain positively for CD20 (Immunohistochemistry, × 400). E. Infiltrating CLL cells stain positively for CD5 (Immunohistochemistry, × 200). F. Infiltrating CLL cells stain positively for CD23 (Immunohistochemistry, × 200)Back to article page
