Histological and immunostained microphotographs of our case of plexiform neurofibroma. (A) The hematoxylin and eosin (H&E)-stained tissue section shows multiple enlarged tortuous nerve fascicles in the subepithelial connective tissue (original magnification, 2×). (B) Medium-power microphotograph shows proliferative tumor Schwann cells containing spindle-shaped to comma-shaped nuclei, a scanty cytoplasm, fibroblasts dispersed in the collagenous fibrous connective tissue stroma, and several tortuous nerve fascicles (H&E stain; original magnification, 10×). (C) The high-power microphotograph shows tumor Schwann cells in the tortuous nerve fascicles (H&E stain, original magnification, 20×). (D) The tumor Schwann cells in the tortuous nerve fascicles and the adjacent tumor Schwann cells in the stroma are all positive for S-100 protein immunostain (original magnification, 20×).
