Small bowel adenocarcinoma (SBA) is a rare primary gastrointestinal malignancy. We present a 60-year old man who developed a cutaneous metastasis of jejunal adenocarcinoma to his neck. This case highlights the clinicopathologic and immunophenotypic features of this uncommon cutaneous metastasis.

OBJECTIVE To quantify the risks of malignancy and mortality in people with coeliac disease compared with the general population. DESIGN Population based cohort study. SETTING General practice research database. PARTICIPANTS 4732 people with coeliac disease and 23,620 matched controls. MAIN OUTCOME MEASURES Hazard ratios for malignancy and mortality. RESULTS Of the 4732 people with coe...

Brunner's gland hyperplasia is a rare cause of duodenal mass and gastrointestinal hemorrhage. Imaging and esophagoduodenoscopic evaluation of this condition are frequently consistent with a duodenal malignancy often resulting in surgical resection. However, the malignant potential of these lesions is still unknown, and most are benign. We report the case of a 74-year-old man who presented with ...

We report a 74-year-old man with Wernicke's encephalopathy (WE) whose only prior illness was peptic ulcer disease. Upper gastrointestinal endoscopy demonstrated gastric ulcer scars accompanied by marked deformity, without pathologic evidence of malignancy. WE due to peptic ulcer disease in previous reports was substantially associated with thiamine deficiency due to recurrent vomiting or surgic...

BACKGROUND/AIMS The accurate preoperative prediction of the risk of malignancy of gastrointestinal stromal tumors (GISTs) is difficult. The aim of this study was to determine whether tumor size and endoscopic ultrasonography (EUS) features can preoperatively predict the risk of malignancy of medium-sized gastric GISTs. METHODS Surgically resected, 2 to 5 cm gastric GIST patients were enrolled...

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in gastrointestinal tracts; however, the synchronous or metachronous coexistence of GIST with additional primary malignancy is not common.Here, we present an unusual case of gastric GIST with metachronous primary lung adenocarcinoma diagnosed during his adjuvant treatment with oral receptor tyrosine kinase inhibitor imat...

INTRODUCTION Aortoesophageal fistula is an uncommon but mortal cause of massive upper gastrointestinal bleeding. The most common causes are thoracic aortic aneurisym, foreign body reaction, malignancy and postoperative complication. It can be seen in different pattern on upper gastrointestinal endoscopy. There are surgical, endoscopic and interventional radiological treatment options, however, ...

Oncological emergencies are defined as acute life-threatening conditions in cancer patients either as a result of the malignancy or as a result of its treatment. In this review, we focus on oncological emergencies associated with gastrointestinal tumors. They can be categorized by their system of origin as hematologic, neurologic or metabolic. Furthermore, we discuss mechanical emergencies such...

Duodenal duplication cysts are a rare subtype of gastrointestinal duplications cysts. Approximately 5% of gastrointestinal duplication cysts occur in the duodenum. An 18-year-old woman presented with epigastric pain and a subjective abdominal bulge. A computed tomography scan was subsequently performed and showed a solid and cystic mass with wall calcifications in the lesser sac of the upper ab...

Seeding of a central nervous system malignancy to the abdominal cavity is an uncommon but well documented complication of a ventriculoperitoneal (VP) shunt. However, the metastasis of a primary gastrointestinal cancer to the skin via a VP shunt is extremely rare. We report the clinical case of an 85-year-old male who presented with a right upper quadrant nodule over his shunt, which on histopat...
