Splenosis masquerading as gastric stromal tumor: A case report

Figure 1 Preoperative abdominal computed tomography scan of the stomach mass. A: Computed tomography (CT) plain scan revealed an approximately 5.64 cm × 4.00 cm irregular soft tissue density (orange arrow) that was not clearly defined from the stomach and pancreas (white arrow). B: Contrast-enhanced CT (arterial phase) revealed that there was slight inhomogeneous enhancement (orange arrow).

Figure 2 Gastroscopic images. Gastroscopy showed an approximately 3.0 cm × 3.0 cm mucosal eminence at the posterior wall of the upper segment of the gastric (white arrow).

Figure 3 Photos of splenosis. A: Intraoperative image. A mass of about 5.0 cm × 3.0 cm was observed between the left upper stomach and the pancreas (white arrow); B: Postoperative specimen.

Figure 4 Photomicrographs (hematoxylin and eosin staining). A: Gastric mucosal epithelium (white arrow) can be seen around the spleen tissue (magnification, × 20); B: Splenic sinus (black arrow), splenic cord, and splenic corpuscle (white arrow) are clearly visible (magnification, × 100).
