Figure 5. Higher PD-L1 expression in inflammatory myofibroblastic tumors with metastasis and recurrence.

Figure 5

Inflammatory myofibroblastic tumors (IMTs) with recurrence and metastasis had significantly greater expression of PD-L1 according to proportion A. and H-score B.. C. A primary tumor that occurred in the maxilla of a 49-year-old man (Case 16). Lung metastasis developed 5.3 months after the initial diagnosis. D. The metastatic lesion has tumor necrosis (inset) and increased tumor cellularity, with more severe nuclear atypia and prominent nucleoli, compared to the primary tumor. Diffuse expression of PD-L1 in primary E. and metastatic IMTs F.. NED: no evidence of disease.
