a High expression (tumor proportion score: 60%) of programmed cell death ligand-1 (PD-L1; clone 22C3) in neoplastic cells; for comparison, see negative staining in normal epithelium (lower left corner). b Next generation sequencing showing the presence of fusion transcript KIF5B–RET (K15; R12)–COSF1232. The gene rearrangement involves the fusion of KIF5B exon 15 and RET exon 12
