Cold agglutinin-associated lymphoproliferative bone marrow disorder. Bone marrow trephine biopsy showing intraparenchymatous nodular lymphoid lesions (panels A and B, H&E staining, 40× and 200×, respectively). Immunoperoxidase staining for CD20 highlights intraparenchymatous nodular B-cell infiltration (panel C, 200×). Mast cells are not discerned around the nodular lymphoid lesions (panel D, Giemsa staining, 200×).
