Gastric stromal tumor: a rare cause of upper gastrointestinal bleeding.

Gastrointestinal stromal tumors (GISTs) are a subset of gastrointestinal mesenchymal tumors, though relatively rare in absolute terms. They are characterized by a remarkable cellular variability and their malignant potential is sometimes difficult to predict. We report a case of gastric stromal tumor in a 66 year old patient with a long history of anemia and intermitent upper gastrointestinal bleeding. We performed upper gastro-intestinal endoscopy, biopsy of gastric mucosa and abdominal ultrasonography to establish the diagnosis. The gastric tumor was successfully resected with a postoperative favourable outcome.
