Gastrointestinal Bleeding due to Duodenal Metastasis of Renal Carcinoma

Abstract

Renal cell carcinoma has the potential to metastasize to almost any organ. However, duodenal metastases are rare and tend to occur when disease is already widespread throughout the body. This article describes a 76-year-old patient with a history of nephrectomy due to renal cell carcinoma, who presented with upper gastrointestinal bleeding. Computed tomography showed a hypervascular nodule in the nephrectomy site, a left adrenal mass and a hypervascular lesion involving the medial wall of the duodenum and extending into the uncinate process of the pancreas. The duodenal lesion was biopsied, confirming the diagnosis of clear cell renal cell carcinoma metastasis.
