case_images: Figure2
case_images: There were patchy dense monotonous lymphocytic aggregates and many separate areas with mixed inflammation including frequent plasma cells, occasional eosinophils, and no neutrophils (Figure 2).
case_images: Kidney biopsy showing atypical lymphocytes in interstitium (A: H & E stain; 100x). Immunohistochemistry markers were positive for CD20 (B: 100x) and cyclin D1 (D: 100x), and negative for CD5 (C: 100x).

case_images: Figure3
case_images: The lymphoid aggregates consisted of atypical mature lymphoid cells with irregular nuclear contours that were predominantly B-cells, positive for CD20 and cyclin D1, negative for CD3, CD5, and CD 10 (Figure 3).
