The sections show paucicellular myxoid material containing polygonal and spindled cells with eosinophilic myxoid cytoplasm, bland nuclei, inconspicuous nucleoli and focal mutlinucleation (myxoma cells). Hemosiderin-laden macrophages, calcified elastic fibres (gamna bodies) and scattered inflammatory cells are also present. There is no nuclear atypia. Mitotic activity is not evident. Several sections show fresh hemorrhage.  The edge has a fibrotic rim and appears to be covered by endothelium. No cardiac muscle is identified.
