Only eight lung carcinomas were examined with IHC using the Visiopharm Image Analysis software (Visiopharm, Hørsholm, Denmark version 2017.27.0.3313), finding that all cases (eight) were positive for HER2, with homogeneous and diffuse labeling of the tumor cell cytoplasm and cell membrane [9]. The gene discussed is ERBB2; the disease is lung carcinoma.
