A Case of Left Atrial Myxoma Whose Initial Symptom Was Finger Ischemic Symptom

We experienced a 45-year-old Japanese man who was transferred to our hospital complaining of acute onset of pain and pallor in the right lower limb. Two years earlier, he had complained of repetitive pain at rest and pallor in the left third and fourth fingers. The physical exam and angiography demonstrated occlusion of finger arteries, however we could not reach final diagnosis. Acute arterial occlusive disease in the right lower limb was suspected. Transthoracic echocardiography demonstrated a gross tumor in the left atrium, which suggested left atrial myxoma. An emergency tumorectomy was successfully conducted. Pathologically, the fragile tumor and resultant thrombosis could have caused the patient's peripheral circulatory failure at least two years prior to this episode. A rigorous systemic survey is important even when the ischemic symptom is localized in peripheral circulation.
