The fine structure of five cases of glomus tumor was described. All of the cases showed a solid type, and the glomus cells were shown to be typical or modified smooth muscle cells. The authors' conclusion is that the glomus cells were not derived from pericytes, but from smooth muscle cells of vascular part of the glomus, and are thought to be a specialized smooth muscle cell tumor.
