A 61-year-old man who had undergone total nephrouretectomy eight months earlier for right ureteral carcinoma was referred for the investigation of elevated serum hepatobiliary enzymes. Computed tomography revealed a small mass invading the lower bile duct. Duodenoscopy revealed a central ulcerative tumor near the major papilla, and a biopsy histologically confirmed metastatic ureteral carcinoma...

Duodenal bile salt concentrations were measured throughout one day in six patients with primary biliary cirrhosis while they were eating a normal ward diet. Five of them had lost weight; none had ascites. Each patient had a radiologically normal small bowel and a normal jejunal biopsy. No clear relationship between high faecal fat excretion and abnormally low duodenal bile salt concentration wa...

Malignant plasma cells in multiple myeloma are predominantly confined to the medullary space of the skeletal system, therefore the disease course will be dominated by signs and symptoms related to bone marrow infiltration and destructive bone lesions with their consequences as well as abnormal protein production. Visceral extramedullary plasmacytoma involving the gastrointestinal system and par...

Duodenal biopsy specimens from 80 patients with chronic renal failure, who were undergoing haemodialysis, were examined by light microscopy for evidence of inflammation, gastric metaplasia, and Campylobacter pylori infection. Chronic duodenitis was present in 47 (59%) of patients, of whom only seven (9%) showed evidence of active inflammation. Gastric metaplasia was present in 50 (62.5%) of pat...

A duodenal polyp was found during a health check of a 71-year-old asymptomatic man. Duodenoscopy demonstrated a pedunculated, smooth-surfaced tumor of 18 mm in size, protruding from the minor papilla. Endoscopic ultrasonography demonstrated a homogeneously low-echoic submucosal tumor. Enhanced computed tomography and magnetic resonance imaging demonstrated a well-enhanced duodenal tumor without...

BACKGROUND Magnification endoscopy (ME), with 115-fold magnification, allows visualization of duodenal villi. We assessed the efficacy of ME for evaluation of villous atrophy. METHODS ME and duodenal biopsy were done in 16 patients with suspected celiac disease and 16 control subjects undergoing endoscopy for reflux symptoms. The pathologist was unaware of the ME findings. RESULTS Sensitivi...

Zollinger-Ellison syndrome (ZES) is caused by hypersecretion of gastrin from duodenal or pancreatic gastrinomas. We report a case of a 57-year-old female who presented with chronic diarrhea. CT abdomen showed multiple liver masses. Liver biopsy suggested metastatic well-differentiated neuroendocrine tumor. Serum gastrin level was markedly elevated. MRI abdomen, somatostatin receptor scintigraph...

brunner’s gland hamartoma is a rare benign tumour of the duodenum. it was first described by cruveilhier in 1835. presently around 200 cases have been reported in literature. no sex predilection is seen. patients usually present in the fifth to sixth decades of life. they may be clinically silent or may present with variable symptoms and occasionally obstructive symptoms and chronic pancreatiti...

Intramural duodenal hematoma (IDH) oc− curs mainly in children, secondarily to blunt abdominal injury. In adults, blunt abdominal trauma accounts for 70 % of IDH cases [1]. Nontraumatic causes of IDH in adults include coagulation disor− ders, duodenal biopsy, and endoscopic in− jection therapy for bleeding ulcers [2]. Very few cases of IDH of pancreatic origin have been reported [3± 5]. We desc...

strongyloidiasis is a frequent misdiagnosed parasitic infection in the world that caused by strongyloides stercoralis . in iran, the disease is predominantly reported from warm and humid climate provinces. the patient was a 54-yr-old man, originated from khuzestan province with a history of pemphigus and diabetes that was treated with high-dose of corticosteroid drugs before admission in a non-...
