Acinar cell carcinoma (ACC) of the pancreas is a rare malignancy making up approximately 1% of pancreatic non-endocrine malignant tumors. The common finding on computed tomography is a solitary, well-defined, heterogenous hypodense mass with enhancing capsule. ACC is a highly cellular tumor with minimal stroma and a lack of stromal desmoplasia. The accurate diagnosis of ACC cannot typically be ...

CONTEXT Pancreatic dermoid cysts are rare, benign, germ cell tumors and part of the differential diagnosis for cystic neoplasms of the pancreas. CASE REPORT A 35-year-old man presented with an incidentally discovered, 2 cm cystic pancreatic neoplasm of the pancreatic tail identified on CT scan. Endoscopic ultrasound (EUS) revealed a complex, honeycomb lesion. Fine needle aspiration (FNA) yiel...

BACKGROUND & AIMS Cysts of the pancreas display a wide spectrum of histology, including inflammatory (pseudocysts), benign (serous), premalignant (mucinous), and malignant (mucinous) lesions. Endoscopic ultrasonography (EUS) may offer a diagnostic tool through the combination of imaging and guided, fine-needle aspiration (FNA). The purpose of this investigation was to determine the most accurat...

Splenic artery aneurysms (SAAs) are an extremely rare cause of asymptomatic massive lower gastrointestinal bleeding with less than a handful of patients surviving such a presentation. A 24-year-old female presented in shock after multiple episodes of massive rectal bleeding. Imaging revealed a heterogeneous mass arising from the tail of the pancreas eroding into the splenic flexure of the colon...

Heterotopic pancreas (HP) in stomach is a rare pathological entity that poses clinical dilemma for diagnosis and management. It carries a risk of developing serious benign and malignant complications. This is a case of 37-year-old lady who presented with dyspeptic symptoms and was found to have a 1.5 cm umblicated lesion in the distal stomach on gastroscopy. Endoscopic biopsy showed normal gast...

AIM Diabetes mellitus (DM), a leading non communicable disease with multiple etiologies is considered as third greatest cause of death in all over the world. During DM, persistent hyperglycemia causes an increased production of free radicals via auto oxidation of glucose and non-enzymatic protein glycation which may lead to disruption of cellular functions and oxidative damage to membranes. The...

The adult pancreas is capable of limited regeneration after injury but has no defined stem cell population. The cell types and molecular signals that govern the production of new pancreatic tissue are not well understood. Here, we show that inactivation of the SCF-type E3 ubiquitin ligase substrate recognition component Fbw7 induces pancreatic ductal cells to reprogram into α, δ, and β cells. L...

Korean wild magpies (Pica pica sericea) were intranasally inoculated with highly pathogenic avian influenza (A/Chicken/Korea/ES/03 virus) (H5N1), which was classified as clade 2.5. We estimated viral replication, death after infection, and histology and immunohistochemistry. This species was highly susceptible to severe infection; 100% of birds died within 5 to 8 d. The virus was detected from ...

As basic knowledge for evaluation of pancreatic toxicity, anatomical structures were compared among experimental animal species, including rats, dogs, monkeys, and minipigs. In terms of gross anatomy, the pancreases of dogs, monkeys, and minipigs are compact and similar to that of humans. The rat pancreas is relatively compact at the splenic segment, but the duodenal segment is dispersed within...

CONTEXT Greater utilization of cross-sectional abdominal imaging has increased the diagnostic frequency of cystic neoplasms of the pancreas. The "International Consensus Guidelines 2012 for the Management of IPMN and MCN of the Pancreas" illustrates a diagnostic and therapeutic algorithm for these lesions based on current knowledge. CASE REPORT We present a case of a 49-year-old woman with tw...
