Fig 2 (A) Interface between intraalveolar deposits and normal lung (hematoxylin and eosin; ×40). (B) Eosinophilic deposits associated with patchy infiltrates of small lymphoid aggregates (hematoxylin and eosin; ×60). (C) Lymphoid aggregates are positive for the B-cell antigen CD20 (immunohistochemical staining, ×200). (D) Immunohistochemical staining for CD138 plasma-cell antigen shows clustered plasma cells admixed with lymphoid aggregates (×250).
