An esophagogastroduodenoscopy (EGD) found a 1.5-cm friable Paris 0-1s lesion (Fig. 1A) arising in one of Barrett's segments of C2M4 on Prague classification (Fig. 1B). Narrow band imaging of the lesion showed amorphous surface pattern (Fig. 1C).
Histopathological examination revealing moderately differentiated adenocarcinomatous glands and well-differentiated neuroendocrine tumor (A, H&E, orig. mag. x 40) that was positive for synaptophysin (B, orig. mag. x 100)

Histopathological examination of the tissue biopsies from the lesion revealed the presence of moderately differentiated adenocarcinomatous glands and well-differentiated neuroendocrine tumor (Fig. 2A, H&E, Orig. mag. x 40). The neuroendocrine tumor component was positive for synaptophysin (Fig. 2B, Orig. mag. x 100) and chromogranin stain.
