LIGHT, ELECTRON MICROSCOPIC AND IMMUNOHISTOCHEMICAL STUDY ON 24 CASES OF ACINIC CELL CARCINOMA OF SALIVARY GLAND / 重庆医科大学学报

ABSTRACT

Light, electron microscopic and immunohistochemical features of 24 cases of acinic cell carcinoma are described. Microscopically, the tumors were composed of acinic cells,clear cells,vacuolated cells, intercalated duct cells and nonspecific glanduar cells. Electron microscopic study revealed some tumor cells contained zymogen granules or tonofilament et al. Immunohistochemical studies showed tumor cells were positive for keratin in all cases, but some tumor cells were positive for vimentin in fourteen cases. Our findings showed tumor cellular components has heterogenity and support the idea of pluripotent duct cell origin of this tumor
