Figure 1. A computed tomographic scan demonstrates a 7 × 5-cm heterogeneous mass involving the third to fourth portions of the duodenum.
Figure 2. An esophagogastroduodenoscopy shows a submucosal mass in the distal duodenum with normal overlying mucosa and an unrelated diverticulum.
The patient underwent exploratory laparotomy at the location of a 7 × 5-cm tumor in the fourth portion of the duodenum, and another 1-cm tumor was identified in the jejunum. Both tumors were resected along with the involved small-bowel segments. The pathologic findings included 7.5-cm and 1.1-cm gastrointestinal stromal tumors (GISTs) with uninvolved surgical margins. The patient had an uneventful postoperative course and was free of disease 6 months after the operation.
