Abstract
- Gastrointestinal stromal tumor (GIST) is the most common non-epithelial tumor of the gastrointestinal tract. GISTs are most common in the stomach, followed by small intestine, colon and rectum, and esophagus. We report a case of duodenal GIST presenting with gastrointestinal bleeding in a 53-year-old male. Upper gastrointestinal endoscopy revealed a protruded mass with central ulceration on the second portion of the duodenum. Spontaneous spurting blood was encountered from the central ulcer of the mass. Abdominal computed tomography scan and celiac angiography revealed hypervascular tumor, located in the second portion of the duodenum. Laparotomy with wedge resection was performed. Histological and immunohistochemical studies on resected specimen revealed a duodenal GIST of a combined smooth muscle and neural type.
