CONTEXT Solid pseudopapillary tumour of the pancreas is an uncommon tumour, which predominantly occurs in young females and is of unknown origin. CASE REPORT We describe five cases with diverse clinical and/or histological features, including one unusually aggressive case resulting in early death. CONCLUSION There is great variability in the presentation and clinical course of these tumours...

endocrine tumors of the pancreas (islet-cell tumors) are rare with neuroendocrine origin. the patient was a 41- year- old man, admitted with chief complains of epigastric mass feeling, dull abdominal pain, lack of appetite and weight loss up to 2-3 kg since 6 months ago. in physical examination, a mass was detected in epigaster and left upper quadrant (luq). in abdominal x-ray, a calcified mass...

background : pancreas as the insulin-producing gland is subjected to destruction and change in the diabetes-producing process. realtime sonography can assess the gland in 95% of cases and its accuracy in diagnosis of pancreatic disease matches that of ct-scan. the purpose of this study was to evaluate pancreatic diameter and echogenicity by sonography and to examine the correlation of these two...

congenital cystic lesions of the pancreas are rare findings. furthermore, dermoid cyst of the pancreas is exceptionally uncommon. a review of the world literature showed that only 18 documented cases of dermoid cyst of the pancreas were reported so far. the pre-operative evaluation of this lesion is rather questionable, with definitive diagnosis taking place intra-operatively. herein, we presen...

background: “teucrium polium l.” (tp) has been long recommended in iranian folk medicine for its anti-diabetic activities. we attempt here to evaluate the effect of tp extract on insulin secretion in rat pancreas. methods: rat pancreas was isolated in situ and perfused with krebs solution containing low glucose (lg, 2.8 mm) or high glucose (hg, 16.7 mm) as perfusate. the aqueous extract (aq. e)...

Acute pancreatitis is an inflammatory condition that may lead to multisystemic organ failure with considerable mortality. Recently, resolvin D1 (RvD1) as an endogenous anti-inflammatory lipid mediator has been confirmed to protect against many inflammatory diseases. This study was designed to investigate the effects of RvD1 in acute pancreatitis and associated lung injury. Acute pancreatitis va...

OBJECTIVES An imbalance of free radicals and scavenging processes has been implicated in the pathogenesis of pancreatic tissue injury. Gradual decreases in antioxidant enzyme expression in pancreatic cells from normal pancreas to chronic pancreatitis to pancreatic cancer have been reported. Zinc is one of the components of antioxidant enzymes and may play a role in the pathogenesis of pancreati...

Anaplastic pancreatic carcinomas are rare tumors, frequently displaying a variety of growth patterns. The literature lacks a comprehensive study of this tumor. Thirty-five cases of anaplastic carcinoma of the pancreas diagnosed between 1955 and 1997 were retrieved from the Endocrine Registry at the Armed Forces Institute of Pathology. Histology, immunophenotype, molecular analysis, and patient ...

CONTEXT Ligation of the pancreatic duct, distally to its confluence into the bile duct has been shown to induce endocrine tissue regeneration. The surplus endocrine tissue formed is presumed to be able to replace pathologically and/or experimentally compromised tissue. OBJECTIVE This is a quantitative study on the histology of duct ligated pancreas employing immunocytochemistry and computeris...
