Immunohistochemical results. a Immunopositivity for cytoplasmic MUC5AC was detected in malignant mucinous cells, with negative staining in malignant epidermoid cells (magnification 400×). b Immunopositivity for membrane MUC1 was detected in all malignant epidermoid cells and mucinous cells (magnification 400×). c Immunopositivity for p63 was only detected in the nuclei of malignant epidermoid cells (magnification 400×). d Cytoplasmic CK19 staining was diffusely positive in the malignant epidermoid and mucous component of the tumor (magnification 400×). e Cytoplasmic CK7 staining was focally positive in the malignant epidermoid and mucous component of the tumor (magnification 400×). f Mucous component of the tumor was focally positive for membrane CEA staining (magnification 400×)
