Figure

• 

  Fig. 1. Abdominal CT showing homogeneously enhancing mass in the distal ileum with multiple lymph node enlargement, small bowel mesentery and mesenteric haziness (arrow).

• 

  Fig. 2. Capsule endoscopic finding. Luminal protruding masses were observed at the ileum.

• 

  Fig. 3. PET-CT showing hypermetabolic malignancy in the ileum with multiple regional lymph node metastasis in the small bowel mesentery (arrow).

• 

  Fig. 4. The small intestinal wall showed five nodular masses, measuring up to 4 × 3 cm in dimension (A), and each of masses had grayish fish-fresh like cut curface (B). (C) On microscope, the tumor was composed of uniform neuroendocrine cells with scant, lightly eosionphilic cytoplasm, arranged in nests and trabeculae (H&E, ×200). The tumor cells invaded through the muscularis propria into the subserosal tissue (inset). (D) The tumor cells showed intense cytoplasmic immunoreactivity with chromogranin A (×200).
