Figure 4

Representative area of nasopharyngeal carcinoma at x20 magnification. The strands of malignant cells can be seen more clearly. In addition to the pale cords and the darker basaloid cells, scattered lymphocytes can be seen (the small dark cells scattered throughout the image, arrows) and deposits of amyloid-like protein (the pink globules forming a band at the top right of the image, arrowheads). (×20 magnification, hematoxylin and eosin stain).
