Figure 3 :Esthesioneuroblastoma: Tumor cells are arranged in lobules separated by vascular and desmoplastic stroma [fi g 3a] (H and E; x4). Tumor cells show rossett e formati on and may have comedonecrosis patt ern [fi g 3b] (H and E; x100). Higher grade tumors of Hyams III and IV grade with cord and trabecular patt ern comprised of blue undiff erenti ated cells in a fi brillary background [fi g 3c] (H and E; x200). Tumor cells show immunoreacti vity for synaptophysin
