RESUMO
Myxoma is the most common benign tumor of the heart, but it is very rare for it to originate from the left atrial appendage. Distinguishing between a mass, a thrombus, and a tumor in the body of the left atrium with preoperative transthoracic or transesophageal echocardiography is very difficult, even more so in patients with mitral valve disease and chronic atrial fibrillation. A 50-year-old male patient was admitted for surgery with the diagnosis of mitral stenosis and chronic atrial fibrillation. Transesophageal echocardiography demonstrated a mass attached to the wall of the left atrial appendage. Histopathological examination of the mass showed an image compatible with a myxoma. We hereby describe a case of a left atrial appendage myxoma mimicking a left atrial appendage thrombus.

Elevated plasma homocysteine (Hcy) is one of the suggested risk factors for endothelial dysfunction. There is evidence of association between raised plasma Hcy and an increased risk of developing peripheral arterial disease. A causal relationship, however, has not been established. In this report, a 37-year old male patient with the complaints of intermittent hand pain is presented. Brachial artery aneurysm accompanying a homozygous methylenetetrahydrofolate reductase mutation was detected.
