title: [Left atrial myxoma with extramedullary hematopoiesis and ossification].
abstract: A 65-year-old female with palpitation was referred to our hospital for a further examination. Trans-esophageal and thoracic echocardiogram demonstrated a left atrial tumor with a patchy calcification, arising from the lower portion of the interatrial septum. It was completely extirpated together with its sessile pedicle and the related disc of interatrial septum. The tumor showed the extensive extramedullary hematopoiesis and ossification around scanty clusters of myxoma cells on light microscopy. These findings indicated further support to the belief that the primitive mesenchymal cell is the origin in cardiac myxoma.
