A case of true malignant mixed tumor of the parotid gland is reported. The tumor,
occuring in a 55-year-old man, started to glow rapidly after a long history of parotid
mass. Total parotidectomy was carried out and the resected tumors measured 5¡¿4¡¿3
§¯ with a cut surface showing grayish-white solid and myxoid appearance.
Microscopically, the tumor had both carcinomatous and sarcomatous elements, the
formed consisting of undifferentiated carcinoma with focal areas of ductal differentiation
and the latter consisting of pleomorphic sarcoma with chondrosarcomatous differentiation.
A remnant of benign pleomorphic adenoma could also be identified. Immunohistochemical
study demonstrated focal cytokeratin reactivity in the carcinoma cells and vimentin in
sarcomatous elements. It is assumed from these clinical and histological findings that the
tumor had transformed from a pre-existing benign pleomorphic adenoma. (Korean J
Patrol 1992; 26: 530¡­ 532)
