Open partial nephrectomy for a collision renal cell carcinoma in a transplant kidney: A case report

Abstract

A collision tumour of the kidney is a very rare condition defined by two immediately adjacent but histologically distinct neoplasms that coexist within one organ without histological admixture. We present a collision tumour in a transplant kidney treated with open partial nephrectomy. This case also highlights key surgical principles the enhanced risk of oncogenesis in transplant recipients, and some key principles for surgical resection of a tumour in a transplant kidney.
