Immunohistochemical expression of EGFR, PDGFRA and VEGFR2 in cervical adenosquamous carcinoma. A) EGFR positive immunoreaction decorating the cytoplasm of malignant cells. No stromal or endothelial positive reactions were observed (original magnification ×40). B) PDGFRA positive immunoreaction was observed in the cytoplasm of malignant cells. PDGFRA positive reaction was also constantly observed in the stromal component, decorating fibroblasts and endothelial cells (original magnification ×40). C) VEGFR2 positive immunoreaction was in the cytoplasm of malignant cells. No stromal positive reaction was identified, but positive staining was observed in a few endothelial cells surrounding the neoplastic cells (original magnification ×40).
