Case Report (n=1)
Highlights a rare presentation of primary malignant fibrous histiocytoma mimicking a left atrial myxoma.
Rare cardiac sarcomas may mimic myxomas; this case extends the differential for left atrial masses extending into pulmonary veins.
A 35-year-old woman presented with 4 months history of progressively increasing intermittent dyspnea and hemoptysis. Transthoracic echocardiography revealed a loculated mass in the left atrium (LA). A provisional diagnosis of LA myxoma was made. Intraoperatively the tumor was found extending into and closely adherent to the left pulmonary vein and could not be completely cleared off from the pulmonary venous wall. The histopathological examination of the tumor revealed it to be a myxoid malignant fibrous histiocytoma.
