case_images: Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) scans showed a 3 x 2-cm, clearly defined, well-enhanced mass adjacent to the duodenal loop in the subhepatic space (Figure 1).
case_images: The pathologic findings were of a well-encapsulated solid mass containing cells with a diffuse, trabecular growth pattern. (x40, H&E).

case_images: Gastrinoma was finally diagnosed by immunohistochemical staining (Figures 2, 3).
case_images: The tumor cells were strongly immunopositive for gastrin. (x250, avidin-biotin-peroxidase).

case_images: Gastrinoma was finally diagnosed by immunohistochemical staining (Figures 2, 3).
case_images: Biopsy of the multiple small nodules revealed the haphazard arrangement of uniform spindle cells in a collagenous stroma. (x100, H &E).

case_images: The pathologic diagnosis was gastrointestinal stromal tumor (GIST) with a low mitotic index as evidenced by C-kit positivity (Figures 4, 5).
case_images: The tumor cells were immunopositive for C-kit (CD117). (x 100, H &E).
