study of the nature of hyaline cells in pleomorphic salivary gland adenomas

ABSTRACT

Twenty two specimens of plemorphic salivary gland adeoma were examined by haematoxylin and eosin, to detect the presence or absence of hyaline cells. Eight cases [36%] exhibited this cell, and gave positive staining results with monoclonal antiacatin antibodies. The dual presence of actin in addition to cytokeratin, which has already been demonstrated in the cytoplasm of these cells in previous studies, supports the hypothesis of a myoepithelial origin for such cells
