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).
