Renal Cell Carcinoma with Cardiac Metastases: A Case Report and Review of the Literature.

Cardiac metastases from renal cell carcinoma (RCC) are very rare. We describe the case of a woman with RCC with cardiac metastases involving the entire right atrium, penetrating through the myocardium, with extension into the tricuspid valve and right ventricle. This report highlights the unique challenge of the diagnosis and treatment of cardiac metastases in RCC.

Metastatic retroperitoneal paraganglioma: Case report and review of the literature.

Paragangliomas are rare neuroendocrine tumors with 500 to 1600 new cases in the United States each year (1). The clinical presentation may range from asymptomatic to the classic triad of episodic diaphoresis, headache, and palpitations. Surgery is the hallmark of treatment when tumors are amenable to resection. When patients are found to have metastases, systemic therapies may be employed. In this case report, we present a patient found to have a large retroperitoneal paraganglioma with nodal metastases.
