Abstract:
Cardiac myxoma is the most common primary tumor of the heart. The tumor contains a variety of cell types that are thought to arise from a focus of primitive pluripotential mesenchymal cells in the area of the fossa ovalis. Throughout the myxoid stroma, there are variable amounts of reticular fivers, collagen, elastic fibers and smooth muscle cells. A 38-year-old female had right atrial myxoma with multiple pulmonary infarcts. In this case, we experienced an unusual degenerative change in the tumor of granulomatous lesion consisting of hemosiderin pigments, foreign body giant cells and peculiar, spheroid, semilunar or bamboo-shaped degenerated elastic fibers. Microscopically it resembles Gamna-Gandy nodule seen in the spleen of chronic passive congestion.
