Abstract
Five cases of mucoepidermoid carcinoma of the parotid gland were studied ultrastructurally.
In addition to epidermoid cells (tonofilament-rich) and mucous cells, three forms
of intermediate cells were identified: mitochondria-rich cells, glycogen-rich cells,
and ribosome-rich cells. Transitional forms of all cell types were observed. Ultrastructurally,
cells rich in glycogen appeared to be the “clear cells” by light microscopy; cells
rich in ribosomes appeared basophilic under light microscopy. Mitochondria-rich cells
were lightly eosinophilic under light microscopy.
