Computed tomography (CT) findings. CT showed a low-density tumor, 3.1 cm in size, in the pancreatic tail (white arrow). An area of lower density, suspected to be necrosis, was seen in the tumor (black arrow) (A). Resected specimen. The tumor was visible on the surface of the pancreas (solid arrow), and had invaded the posterior stomach wall (dotted arrow) (B). Macroscopic findings of resected tumor. Macroscopically, the tumor was yellowish-white and well demarcated (white arrow), and intratumoral necrosis was present (black arrow). The tumor had invaded the stomach wall (dotted arrow) (C). Microscopically, the tumor was characterized by extensive cellularity and minimal desmoplastic stroma, and the tumor cells were arranged in a solid pattern. The nuclei showed only moderate atypia, and eosinophilic granules were frequently seen in the cytoplasm (hematoxylin and eosin; original magnification x40) (D).

Contrast-enhanced computed tomography (CT) showed a well-demarcated low-density tumor, 3.1 cm in size, located in the pancreas tail (Figure 1A). Although surgery was unlikely to be curable, the disseminated nodules were localized, and distal pancreatectomy, concomitant with partial gastrectomy and resection of the disseminated nodules, was performed (Figure 1B). Macroscopically, the pancreatic tumor was yellowish-white and well demarcated (Figure 1C). Microscopically, the tumor was characterized by extensive cellularity and minimal stroma, and the tumor cells were arranged in a solid pattern (Figure 1D).
