Case 100
Case contributed by Dr. Maurício Sérgio Brasil Leite of Goiânia, Goiás, Brazil
There is a mass lesion involving the left atrium, with a thrombus in the right atrium, from a 55 year old woman. The mass is white to tan and irregular, invading adjacent structures. Microscopically, there are spindle to oblong cells with hyperchromatism and pleomorphism. Focally, pink osteoid is present. There were microscopic metastases to the lung. Primary cardiac osteosarcomas are rare, accounting for only 1% of all cardiac tumors, and they usually originate in the left atrium. Calcifications may be present. Mestatatic osteosarcomas usually involve the right side of the heart. Primary cardiac tumors can mimic many other cardiac conditions and may cause obstruction to blood flow, heart failure, chest pain, syncope, pulmonary hypertension, and arrhythmias. CT scanning may be useful to determine the location and composition of a cardiac mass.
