[Electron microscopy and histochemical studies of the origin and function of myoepithelioid cells in glomangioma and peripheral barrier arteries].
Epithelioid cells (myoepithelioid cells, glomus cells) are a structural element characteristic of Hoyer-Grosser shunts (glomus organs, arterio-venous epithelioid cell glomerula) and Bailey's glomangioma (Masson's angio-neuromyome-artériel, glomus tumors). Their functional importance cannot be estimated without knowledge of their histogenetic origin. The myoepithelioid cells are derived from smooth muscle cells, which can be shown ultrastructurally, histochemically, or by light microscopy.
