Fig 3 (A) Section showing the mitral valve with proliferation of small- to medium-sized atypical lymphoid cells, accompanied by aggregates of epithelioid histiocytes (hematoxylin and eosin, ×400). Immunohistochemically, these atypical lymphoid cells were positive for (B) CD3, (C) CD4, and (D) CD8 (immunohistochemically staining, B ×400; C ×200; D ×200).
