(A) Abdominal CT showing a well‐circumscribed tumor in the 4th portion of the duodenum (white arrow). (B) Note an enhanced nodule over the right side of the pelvis abutting the posterolateral wall of the bladder (black arrow). (C) Enteroscopic examination showing an ulcerated mass over the 4th portion of the duodenum. (D) HE stain of the duodenal tumor showed hyperplastic cells featuring uniform ovoid nuclei in ribbons, solid nests or pseudo‐glandular pattern. (H&E ×40). The tumor cells were positive to synaptophysin (E) and chromogranin‐A (F), and negative to CD117 (G) and cytokeratin (H). Positive nuclear immunoreaction for Ki 67 (I) was about 3% of cells. S100 immunostaining (J) indicates the sustentacular cells (×200)
