Cervical histopathology and immunohistochemical images. (A) A right cervical lymph node biopsy specimen reveals effacement of the normal architecture with abundant pleomorphic cells and marked proliferation of arborizing high endothelial venules (hematoxylin and eosin stain, ×100). (B) Pleomorphic cells composed of lymphocytes, eosinophils, and atypical cells with intermediate-sized nuclei and clear cytoplasm are evident (hematoxylin and eosin stain, ×400). (C) Immunohistochemical examination shows CD3 positive staining in lymphocytes and atypical cells (×400). (D) A bone marrow aspiration smear reveals normal bone marrow (May-Giemsa stain, ×100).
