Myoepithelial adenoma
The smears show monomorphous spindle-shaped or plasmacytoid cells, clean background, no or just very little normal salivary gland epithelium. The chondromyxoid stroma is not present (if present, the tumor is called 'mixed tumor'). The nuclei are round or elongated. No mitotic figures are present. Metachromatic fragments may be found, but they do not correspond to the large amount of metachromatic stroma of the mixed tumor!
