Immunostaining for EPOR expression in oral squamous cell carcinoma. (A) The representative tumor shows only weak EPOR immunoreactivity in the neoplastic epithelial cells at the border of the tumor. (B) The representative tumor exhibits diffuse and strong EPOR immunoreactivity in the neoplastic epithelial cells. Note that some inflammatory cells are also positive for EPOR.
