Arterial tumor embolism caused by metastatic melanoma: case report and literature review.

Arterial tumor embolization is a rare complication of neoplasms. This report describes a 64-year-old female with metastatic melanoma and acute arterial embolization to the left lower extremity. With surgical embolectomy, a clot was retrieved that had an atypical bland solid lead point. Pathologic examination confirmed metastatic melanoma. Further echocardiography revealed an intracardiac mass consistent with metastatic disease. The patient was seen a month later with embolization to the right middle cerebral artery.
