BACKGROUND Magnifying endoscopy with narrow-band imaging (ME-NBI) is a novel, image-enhanced endoscopic technique for differentiating gastrointestinal neoplasms and potentially enabling pathological diagnosis. OBJECTIVES The aim of this analysis was to assess the diagnostic performance of ME-NBI for gastric neoplasms. METHODS We performed a systematic search of the PubMed, EMbase, Web of Sc...

Gastrointestinal mesenchymal tumors are a group of tumors originated from the mesenchymal stem cells of the gastrointestinal tract, consisting of gastrointestinal stromal tumors (GIST), leiomyomas or leiomyosarcomas or schwannomas. Gastric schwannoma is a very rare gastrointestinal mesenchymal tumor, which represents only 0.2% of all gastric tumors and 4% of all benign gastric neoplasms. We rep...

......................................... Received: 19-07-13 Accepted: 21-07-14 Abstract Helicobacter pylori are gram-negative bacteria that colonize the gastric epithelia of approximately 50% of the world’s population. This infection is considered to be the leading known cause of chronic gastritis, peptic ulcers, gastric MALT and gastric cancer. In addition, there is evidence linking the bacte...

A schwannoma is a kind of neurogenic tumor that rarely occurs in the gastrointestinal tract. Gastric schwannomas make up 0.2% of all gastric neoplasms. Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors and up to 60-70% of GIST occur in the stomach. Schwannoma and GIST are similar in clinical features, so they are difficult to differentiate preoperatively. Differentia...

INTRODUCTION Secondary bladder neoplasms are uncommon and they represent only 2% of all malignant bladder tumors. CASE PRESENTATION The authors present a case of a 59-year-old Caucasian man with a primary gastric adenocarcinoma that had been surgically removed 10 years before he developed bladder metastasis. He presented with low abdominal pain after 10 years without any symptoms. Cystoscopy ...

Gastric glomus tumors are rare, mesenchymal neoplasms, generally described as benign and account for nearly 1% of all gastrointestinal soft tissue tumors. The most common gastrointestinal site of involvement is the stomach, particularly the antrum. Gastric glomus tumors are submucosal tumors that lack specific clinical and endoscopic characteristics, and are often mistaken for the more common g...

A 67 year old female was referred because of an incidentaloma on CT-scan and MRI which showed a 5.0 cm large mass in the wall of the distal stomach. After an initial work-up which suggested a gastrointestinal stromal tumor (GIST), a partial gastrectomy with a Billroth II gastrojejunostomy was performed. The histological diagnosis was a schwannoma. Gastric schwannomas are rare tumors which compr...

INTRODUCTION Scleromyxedema is a rare, chronic and progressive disorder of unknown origin characterized by a generalized papular eruption and sclerodermoid induration, with histopathologic features of mucin deposition and fibroblast proliferation. The disease is usually associated with a monoclonal gammopathy. However, only a few cases associated with neoplasms have been reported. We report a c...
