ABSTRACT
BACKGROUND/AIMS: Endoscopic ultrasonography (EUS) has been useful in evaluating submucosal lesions of the upper gastrointestinal tract as well as providing guidelines for therapeutic plans. Large proportions of submucosal tumors are diagnosed as stromal tumors. Most are benign, but a significant proportion of them could be malignant. There are a few reports concerning EUS findings as being predictive of malignancy. The aim of this study was to evaluate specific EUS features favoring malignancy in stromal tumors of the UGI tract. METHODS: From January, 1992 to June, 1997, thirty-three cases appeared involving stromal tumors (18 benign, 15 malignant (including 8 STUMP)), and were either surgically (27 cases) or endoscopically (6 cases) resected. Videotapes and photographs were reviewed and EUS features that favored the malignancy were analyzed.

BACKGROUND/AIMS: A gastric aberrant pancreas can be easily diagnosed through con- ventional endoscopy and radiologic modalities due to its characteristic features such as central dimpling. However, in cases involving an aberrant pancreas without the central dimpling, the differential diagnosis has been some troublesome. As for differential diag- nosis of gastric submucosal tumors, endoscopic ultrasonography (EUS) allows us to visu- alize the structures underlying the gastrointestinal wall in a non-invasive manner, and has a great advantage over conventional modalities such as conventional endoscopy or the UGI series. METHODS: We studied the EUS findings of a gastric aberrant pancreas without the central dimpling. We compared EUS features in 10 cases involving a gastric aberrant pancreas without the central dimpling to those in 16 cases with the central dimpling.

Granular cell tumors (GCT), previously termed granular cell myoblastorna, was first described as a myoblastic myoma of the tongue in 1926 by Abrikossoff and has been reported in many different locations throughout the body. In 1931, Abrikossaff described the first granular cell tumor of the esophagus. The gastrointestinal tract is one of the more uncommon locations for granular cell tumors. Until recently, granular cell tumors had been considered rare but, the incidence of granular cell tumors has been slowly raising since endoscopy has been used more commonly as a diagnostic tool. In this study, we report three cases of esophageal granular cell tumors which were successfully diaganosed by an esophagoscopy and an endoscopic ultrasonography and confirmed using an endoscopic esophageal mucosal resection (EEMR).
