case_images: The cut surface was composed of pale yellow-grey soft tissue with foci of haemorrhage.  The tumor was limited to mesentery without extension to the ileal wall.  Microscopic examination revealed cellular lobules with nests and poorly developed tubules of Sertoli cells (Figure 1) that showed moderate atypia and mitotic figures that average 5-10 per high-power field (Figure 2).
