Chondrosarcoma simulating malignant atrial myxoma
GL Hammond, WW Strong, LS Cohen, M Silverman, R Garnet, VA LiVolsi and JL Cornog
A 69-year-old patient underwent removal of a left atrial tumor which was
diagnosed clinically and pathologically as atrial myxoma. Fourteen, 18 and
22 months later, distant metastases were discovered. Two of the metastases
were removed entirely and one partially. The metastatic tumors were also
thought to be of myxomatous origin by light and electron microscopy. Only
at autopsy was it demonstrated that the patient had a primary
chondrosarcoma of the pelvis giving rise to widespread myxoid metastases to
the heart and other sites.
