ENDOSCOPIC ULTRASONOGRAPHY FINDINGS OF TWO CASES WITH NONFUNCTIONING ISLET CELL CARCINOMA OF THE PANCREAS -COMPARISON TO PANCREATIC DUCTAL CANCER-

Abstract

We examined the endoscopic ultrasound (EUS) findings of 2 cases of nonfunctioning islet cell carcinoma of the pancreas (NFICC), comparing to those of pancreatic ductal cancer (n=87). There were no useful EUS findings for differential diagnosis between NFICC and pancreatic ductal cancer, in regard to heterogeneity of internal echo, clearness of boundary echo, no ductal structure in tumor, or no penetrating duct sign. Regular peripheral ehco and round or oval tumor shape may be characteristic EUS findings of NFICC.
