Tumor Seeding of Percutaneous Nephrostomy Tract from Urothelial Carcinoma of the Kidney

Abstract

Urothelial carcinoma (UC) of the renal pelvis has been rarely shown to metastasize to the skin. Tumor seeding from iatrogenic procedures is a source of spreading of UC to the skin. We herein present a case of primary UC of the renal pelvis with spreading to the skin from a percutaneous nephrostomy tract.
