Abstract

We report a relatively rare case of duodenum gastrointestinal stromal tumor(GIST)treated by surgery. The patient was a 64-year-old woman who presented anemia; Esophagogastroduo-denoscopy(EGD)revealed a tumor of duodenum with oozing bleeding, and she was referred to our hospital for further examination and treatment. Abdominal CT images showed a mass that was located forward of the duodenum and 85mm in diameter. EGD revealed a duodenal submucosal tumor and GIST was diagnosed by endoscopic biopsy. The tumor was resected at laparotomy and histologically classified as high risk group. Therefore, we added adjuvant chemotherapy by imatinib. We followed up the patient without recurrence.
