| Research Abstract |
In a tumor of salivary gland, a pleomorphic adenoma is a benign tumor with the highest frequency, and when it passes at a long period of time, carrying out malignant alteration is known. The cause which a benign tumor transforms into a malignant tumor was searched using the atypical pleomorphic adenoma and carcinoma ex pleomorphic-adenoma to which the benign part and the malignant part are intermingled in the same tumor. The part as which the malignant tumor was regarded showed p63 immunohistochemical staining and EMA immunohistochemical staining were positive, what both the myoepithelial cell and the ductal-epithelium cell transformed became clear, and it checked that the protein which participates in DNA repair protein or cell cycle related protein were over expressed by those parts.
