Both EGFR and HER-2 expressions in the same patients were observed in 12 cases (18%) (Figures 1 and 2), in which expressions of both EGFR and HER-2 were seen in the same tumour regions in two cases (Figure 1), and EGFR and HER-2 expressions were seen in individually distinct regions in nine cases (Figure 2). The gene discussed is ERBB2; the disease is neoplasm.
