A neuroendocrine neoplasm (nen) is a tumor that originates in neuroendocrine cells capable of producing peptides or amines. neuroendocrine neoplasms of the digestive system are also referred to as gastroenteropancreatic neuroendocrine neoplasms (GeP nen) and constitute a heterogeneous group of growths originating from at least 15 types of specialized cells spread throughout the stomach, small i...

Schwannomas are generally slow growing asymptomatic neoplasms that rarely occur in the GI tract. However, if found, the most common site is the stomach. Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and 60-70% of them occur in the stomach. Owing to their typical presentation as submucosal neoplasms, gastric schwannomas and GISTs ap...

Intraductal papillary mucinous neoplasms of the pancreas (IPMNs) are potentially malignant intraductal epithelial neoplasms which consist of columnar, mucin-containing cells and arise from the epithelium of the main pancreatic duct or its branches. IPMNs as well as pancreatic intraepithelial neoplasias (PanINs) and mucinous cystic neoplasms represent noninvasive precursors of invasive ductal ad...

PURPOSE The purpose of this study was to identify the factors influencing quality of life after analyzing the relationship between depression, health promotion and quality of life in patients with gastrointestinal neoplasms. METHODS The subjects of this study were 63 people who underwent treatments from 2 general hospitals in Seoul and Daejeon and had no recurrence in stages I & II of gastroi...

BACKGROUND Altered expression of lamins A/C and B1, constituent proteins of the nuclear lamina, may occur during differentiation and has also been reported in primary lung cancer. AIMS To examine the expression of these proteins in gastrointestinal neoplasms. PATIENTS Archival human paraffin wax blocks and frozen tissue from patients undergoing surgical resection or endoscopic biopsy. MET...

Leiomyomas are benign neoplasms that are thought to originate from the vascular smooth muscle. They have a propensity to arise from the gastrointestinal tract, female genital tract (uterus) and subcutaneous tissue. The nasal cavity is an uncommon site for a leiomyoma. We report a 24-year-old woman with a rare nasal leiomyoma. A brief review of the literature and histological variations are desc...

Video capsule endoscopy is now a first-line tool in evaluating and diagnosing gastrointestinal bleeding, inflammatory bowel disease, and small bowel neoplasms. Capsule nonpassage or retention is an uncommon but clinically significant occurrence. How to best retrieve these retained capsules is currently being debated. We report a laparoscopic approach for the retrieval of a retained capsule in t...

Malignant melanoma of the gastrointestinal tract is an uncommon neoplasm that could be primary or metastatic. Small intestine represents the most common site for the metastatic melanoma; however, it could be found anywhere in the gastrointestinal tract. Intussusception is a rare cause of intestinal obstruction in adults compared to children. In 90% of the cases, the underlying cause can be foun...
