Downhill esophageal varices caused by benign giant lymphoma: Case Report and Review of Downhill Varices Cases in Japan

Abstract

Incidentally detected “downhill” varices of the entire esophagus in a 26-year-old man were found to be due to a benign giant lymphoma in the posterior mediastinum. The superior vena cava was not obstructed. Following resection of the tumor the varices disappeared. Substantial blood drainage to the esophageal veins was assumed to be the causal mechanism.

Key Words:

• downhill esophageal varices
• benign giant lymphoma (angiofollicular lymph-node hyperplasia)
