IVC thrombectomy and atrial tumor removal with radical nephrectomy and adrenalectomy for metastatic melanoma with immune checkpoint inhibitor therapy: A case report and literature review.

Caval thrombus with intracardiac involvement is a rare condition that is associated with renal cell carcinoma. Few reports in literature describe this presentation with metastatic melanoma. Metastatic melanoma is known to involve the adrenal gland, although associated tumor thrombus extension into the renal vein and inferior vena cava is extremely rare. In this case report, we describe radical nephrectomy and adrenalectomy for metastatic melanoma.
