Discordant case between FISH and immunohistochemical Ventana assay: a L700: The FISH assay indicated an ALK fusion gene, but immunohistochemical staining using the Ventana protocol demonstrated no relevant protein expression. b Ö82: This case was negative with the FISH assay, but showed a clear positive staining with the Ventana and the in house assay. The scale bar in the FISH and IHC images represents 10 and 100 μm, respectively
