In the present study, the neoplastic myoepithelial cells in five pleomorphic adenomas of parotid gland were labeled with actin, myosin, S-100 protein, glial fibrillary acidic protein (GFAP) and vimentin. We have found that the neoplastic myoepithelial cells have many different morphologic features, they are the principal proliferating cells in the tumors. In the myxoid region, part of the neoplastic myoepithelial cells have early chondroid differentiation, this shows that the neoplastic myoepithelial cells take the important role in the histogenesis of the tumors.

UI	MeSH Term	Description	Entries
D008949	Adenoma, Pleomorphic	A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth.
