Overexpression of epidermal growth factor receptor (EGFR), as in our case (Figure 3(d)), has been found in various epithelial malignancies, including head and neck squamous cell carcinoma (HNSCC), and is associated with increased tumor growth, metastasis, resistance to chemotherapeutic agents, and poor prognosis [8]. Here, EGFR is linked to head and neck squamous cell carcinoma.
