title: Case of left atrial metastasis of a sarcomatoid carcinoma.
abstract: Metastatic tumor involvement of the heart may occur with all types of primary neoplasms. Right atrial cardiac metastases following vena cava extension from renal cell carcinoma are well recognized, while a left atrial appearance is extremely rare. We report on a patient who developed a left atrial mass originating from the lower right pulmonary vein after successful resection of a renal cell carcinoma with sarcomatoid areas by right-sided nephrectomy. To our knowledge, this is the first described case of this type of pancytokeratin-expressing tumor in the literature so far.
