A case of fibrosing mediastinitis with obstruction of superior vena cava and downhill esophageal varices: a rare cause of upper gastrointestinal hemorrhage.

Fibrosing mediastinitis (FM) is an excessive fibrotic reaction that occurs in the mediastinum and may lead to compression of mediastinal structures (especially vascular or bronchial). In the present study we describe the first case report of FM, in a patient who developed downhill esophageal varices and bleeding, which was secondary to superior vena cava obstruction.
