A case of myoepithelioma of the palate is presented. Histologically, the tumor consisted of slender, spindle‐shaped cells, arranged in closely packed interlacing bundles separated by slender sheets of collagenous stroma. Histochemical studies disclosed high levels of alkaline phosphatase and adenosine triphosphatase activity. Ultrastructurally the cells contained many slender, longitudinally‐oriented filaments approximately 60 Å in diameter. Numerous mature desmosomes were present between tumor cells. The light microscopic, histochemical, and ultrastructural features are considered compatible with the diagnosis of benign myoepithelial cell tumor.
