[Glandular myxoma of the heart]
Abstract:
Light microscopic, immunohistochemical and ultrastructural studies were performed on a surgically removed left atrial myxoma containing glandular structures. Routine examination showed glandular lumina lined by cylindric epithelium in the characteristic myoxoid stroma, and the glands contained PAS positive mucin. The glandular structures demonstrated significant positivity for wide-spectrum-CK, EMA, and moderate positivity for CEA. Stromal cells were positive for vimentin, FVIII. Ag was present only in surface cells and blood vessels. Ultrastructurally the gland showed characteristics of mucin secreting epithelium. The authors briefly overview the currently existing theories about the histogenesis of myxomas.
