title: [Ultrastructure of an atrial myxoma (author's transl)].
abstract: Electron microscopic examination of a surgically removed atrial myxoma showed, besides fibrocytes and fibroblasts, mainly isolated smooth muscle cells arranged in solid cellstrands. They are responsible for collagen-and elastin-synthesis. They are presumed to arise from subendocardial smooth muscle cells and considered to be neoplastic.
