| Popis: | A 62-year-old woman was evaluated for iron deficiency anemia. She had no history of any medications, trauma, smoking, or alcohol consumption. On physical examination, the patient had a pale appearance, and tenderness in the epigastric region but no rigidity or rebound. Upper gastrointestinal endoscopy revealed the majority of the stomach and duodenal bulb to be normal. However, a well-hidden, red-colored, ulcerated lesion (diameter 2cm) was observed. The lesion was located mainly on the posterior side of the duodenal bulb, partly occupying the duodenal bulb, and extended to the descending duodenum (●" Fig.1 and●" Video 1). The appearance and size of the lesion suggested a gastrointestinal stromal tumor (GIST), and it was therefore removed surgically. Histopathological examination of the resected tissue confirmed GIST. The patient was discharged 3 days after the surgery, and was doing well at follow-up. GISTs are the most common submucosal tumors of the gastrointestinal tract, representing 1%–3% of gastrointestinal malignancies. About 50%–60% of GISTs occur in the stomach, and about 20%–30% are malignant [1]. The duodenum is an uncommon location. Diagnosis of duodenal GIST is sometimes difficult, especially those arising in the posterior duodenal bulb. As peristalsis allows a better view of the duodenal bulb mucosa, observation of this area for a while during endoscopic examination is a feasiblemethodofdetecting hidden lesions. |
