The light-and electron-microscopic structure of the glomus tumor of the palate of a 20 years old male was described.
Light-microscopically the tumor was composed of epithelioid cells with round or ovoid nuclei and clear cytoplasm, and the 3 types of microscopic appearance-solid, angiomatous, mucoid-hyaline-were observed.
Electron-microscopically the tumor cells did not show a typical smooth muscle cell appearance, but a modified smooth muscle cell appearance.
