  		FIG 1. Images of a 65-year-old man who presented with a 6-month history of a right frontoparietal nodule that included ulcers and a 1-month history of swelling on the right lid.

A, Unenhanced sagittal T1-weighted MR image does not show any cranial invasion.

B, Contrast-enhanced sagittal T1-weighted MR image shows strong enhancement of a diffuse mass in the scalp bilateral frontoparietal region and invasion of the dura and left gyrus frontalis medius.

C, Coronal view T2-weighted image shows isointense lesion and peripheral hyperintense edema on the left medial frontal gyrus.

D, Sagittal T2-weighted image shows hyperintense edema on the frontal lobe.

E, Contrast-enhanced coronal T1-weighted image shows marked enhancement at the right lateral orbital wall and muscle rectus lateralis.

F, Axial fluid-attenuated inversion recovery image shows invasion of orbital wall (arrow) and muscle (arrowheads).

G, Photomicrograph of a specimen shows tumoral cells (stars) in stratified squamous epithelium (arrows) (hematoxylin and eosin; original magnification, x200).

H, Photomicrograph shows CD20-positive tumoral cells (arrowheads) (strep ABC; original magnification, x100) and stratified squamous epithelium (arrows).
