Abdominal computed tomography (CT) revealed bilateral subphrenic fluid without free air and high concentrations of fluid in the pelvis, which was suggestive of hemoperitoneum (Fig. 1a and b).
Laparoscopic exploration revealing hemorrhagic ascites in the entire abdominal cavity.

Laparoscopic exploration revealed hemorrhagic ascites in the entire abdominal cavity (Fig. 2).
(a) A small ruptured mass is observed in the middle of the small intestine. In the figure, a massive hematoma attached to the mass is already removed. (b) The tumor grows exophytically, and the mucosal side of the resected small intestine is clear.

A small, ruptured mass with a massive hematoma was found in the middle of the small intestine (Fig. 3a). The tumor grew exophytically, and the mucosal side of the resected small intestine was clear (Fig. 3b).
(a) Hematoxylin-eosin staining reveals a bundle-like growth of the spindle-shaped tumor cells with acidophilic cytoplasm and enlarged nuclei with increased chromatin. (b) An intratumoral hemorrhage is noted (arrows). (c), (d) Immunohistochemical staining showing that the tumor is positive for KIT (c) and CD34 (d).

Hematoxylin-eosin staining revealed a bundle-like growth of the spindle-shaped tumor cells with acidophilic cytoplasm and enlarged nuclei with increased chromatin (Fig. 4a). Hemorrhage within the tumor was noted (Fig. 4b), and the mitotic count was 3 per 50 high-power fields. Resection margins were free of the tumor cells, and immunohistochemical staining revealed that the tumor was positive for KIT and CD34 and negative for desmin and S-100 proteins (Fig. 4c and d).
