The sections show paucicellular myxoid material containing spindled-to-epithelioid cells with eosinophilic myxoid cytoplasm and bland nuclei (myxoma cells). Hemosiderin-laden macrophages, calcified elastic fibres and scattered inflammatory cells are also present. There is no nuclear atypia. Mitotic activity is not evident. | The sections show paucicellular myxoid material containing spindled-to-epithelioid cells with eosinophilic myxoid cytoplasm and bland nuclei (myxoma cells).
