Abstract
The patient had a tumor in the right and left atria which arose from the atrial septum and in many ways resembled a myxoma. The microscopic appearance of the tumor was that of epithelial heterotopia, with gland-like spaces lined by mucus-secreting epithelium. Brief reference is made to similar previously reported patients and to the pathogenesis of the condition.
