Figure 2 An abdominal computed tomography shows a low density, 2. 4 cm × 3.0 cm intramural mass of gastric antrum with tiny ulceration (arrows), which is suggestive of a gastric submucosal tumor, such as gastrointestinal stromal tumor. A: Cross section; B: Coronal section.
Figure 3
Figure 3 Upper gastroenterography shows a lesion in the gastric antrum (arrows). The antrum was partially obstructed by the mass.

Figure 4 Pathological manifestation of the neoplasm. A: Microscopcally, the tumor is composed of irregular sheets of cells with a high-grade nuclear atypia (HE stain, × 100); B: Immunohistochemically, the tumor cells are immunoreactive for cancer antigen 125 (× 100).
