Primary splenic lymphoma complicated by hematemesis and gastric erosion.

Gastrosplenic fistula resulting from erosion of a primary splenic lymphoma is a rare cause of massive upper gastrointestinal hemorrhage associated with benign peptic ulcer disease, gastric Crohn's disease, gastric adenocarcinoma, and primary gastric and splenic lymphomas. Upper intestinal hemorrhage can be successfully treated with splenic artery embolization, followed by splenectory and gastric resection.
