The MLCs were positive for CK7, TTF-1, napsin-A, and E-cadherin (a–d). Vimentin was always positive in the MLCs (e). β-Catenin showed membranous staining in all cases (f). The MLCs were negative for p63 (g). ALK immunopositivity showed cytoplasmic granular staining in a case harboring ALK-EML4 fusion (h). Her-2 immunopositivity showed membranous staining in the case harboring HER2 amplification (i).
