This tumor was positive for Sal-like protein 4 (SALL4), cluster of differentiation (CD) 117, and Octamer binding transcription factor (OCT) 3/4 as shown in Figure 2, and was negative for CD30 and Glypican-3 as shown in Figure 3, which further characterized this tumor as a seminoma histologically. Here, TNFRSF8 is linked to neoplasm.
