Hematemesis, a Rare Presentation for Downhill Esophageal Varices.

Downhill esophageal varices (DEV) are a rare form of esophageal varices associated with superior vena cava obstruction. Obstruction leads to retrograde blood flow through collateral venous channels, including the esophageal venous plexus, to redirect blood flow to the right atrium via the inferior vena cava. This leads to the formation of DEV. It is a rare phenomenon to have gastrointestinal bleeding, especially hematemesis, on a patient's first presentation with this disease process. We describe such a case here involving a patient with DEV secondary to metastatic renal cell carcinoma presenting with hematemesis.
