Pancreatic cysts >1 cm lined by nonpapillary mucinous epithelium without ovarian-type stroma pose diagnostic challenges. The term "simple mucinous cyst" was recently proposed for this entity. Our goal was to determine the clinicopathologic characteristics of these cysts, as they have not been previously described. Of the 39 patients with pancreatic resections included in this study, the mean age was 65 years and the female-to-male ratio was 4:1. The characteristics of the cysts are as follows: 82% had elevated cyst fluid carcinoembryonic antigen levels, 67% were unilocular, 69% occurred in the body/tail, 92% did not communicate with pancreatic ducts, the mean size was 2...

Pancreatic endometriosis is very rare with only a few cases reported in the literature. The imaging features are non-specific and the definitive diagnosis is usually only established after surgery. We report on a 68-year-old woman with left upper quadrant pain who demonstrated a mass in the pancreatic tail on imaging. Laboratory results showed only mildly elevated liver enzymes, tumor markers were within the normal range. A left pancreatectomy was performed, frozen section suggesting a benign lesion, and final histopathology confirmed endometriotic cysts...

We describe a hernia of the swim bladder, with a concurrent mycotic granulomatous inflammation, and carcinoma of the swim bladder in a wild mullet (Mugil cephalus) referred for an exophytic dorsal mass. Grossly, the mass was white, soft, and composed of multiple cystic gas-containing chambers connected by a funnel-shaped tissue segment to the coelomic swim bladder. Histologically, the mass was characterized by cysts of variable size, multifocally contiguous with the subepithelial rete mirabile, supported by abundant fibrous tissue...

Mucinous cystic neoplasms (MCNs) can occur in the pancreas and liver. Classically, these cystic lesions are lined by columnar mucinous epithelium with underlying ovarian-type stroma. It has been proposed that cysts with ovarian-type stroma and nonmucinous epithelium be considered separate entities in both the pancreas and liver. Using a series of 104 pancreatic and 32 hepatic cases, we aimed to further characterize the epithelium present in MCNs. Mucinous epithelium was defined as pancreatic intraepithelial neoplasia-like columnar cells with pale pink/clear apical mucin...

The aim of this study was to present a case of enteric duplication cyst and criteria for a proper differential diagnosis. A 51-year-old male was hospitalized for pancreatic tail neoplasm and distal pancreatectomy with splenectomy was performed. During surgery, a jejunal cystic lesion was incidentally detected and jejunectomy was performed. Microscopically, the cyst was observed to be covered by Keratin 7/Keratin 20 positive intestinal type epithelium and the muscularis layer was shared by the cyst and adjacent jejunum, without a cleavage plane between the cyst wall and jejunal muscularis propria...

BACKGROUND: After an acute attack of pancreatitis, walled-off pancreatic fluid collections (PFC) occur in approximately 10 % of cases. Drainage of the cavity is recommended when specific indications are met. Endoscopic drainage has been adopted as the main intervention for symptomatic walled-off PFC. Altered gastric anatomy in these patients poses an interesting challenge. We present the first case of a patient with sleeve gastrectomy who underwent successful endoscopic transduodenal necrosectomy (TDN)...

BACKGROUND: Lymphoepithelial cyst (LEC) of the pancreas is a rare benign tumor. LEC with sebaceous glands of the pancreas is extremely rare, and its histogenesis remains unclear. CASE PRESENTATION: We present a 66-year-old man with an incidental finding of a cystic lesion at the neck of the pancreas. Pancreatic juice cytology results and elevated serum carbohydrate antigen 19-9 and Dupan-2 levels indicated that the cyst was a potential adenocarcinoma. Therefore, a pancreaticoduodenectomy was performed...

A 58-year-old man, who had presented with a large cyst between the pancreatic tail and splenic hilum 6 years previously, was referred to our hospital with exacerbation of abdominal distention. Computed tomography revealed a well-demarcated, unilocular cyst, with a beak sign for the pancreas, without wall thickening or nodules suggestive of a non-neoplastic cyst. Compared with 6 years previously, the cyst had increased in size from 14.7 cm to 19.5 cm, and the serum carcinogenic antigen 19-9 level had increased from 635 U/mL to 1,918 U/mL...

Von Hippel-Lindau disease is an autosomal dominant syndrome which occurs secondary to germline mutations in the VHL tumor suppressor gene, located on chromosome 3. Clinically von Hippel-Lindau disease is characterized by an increased risk of developing simple visceral cysts, most commonly in the pancreas and kidneys, in addition to an increased risk of developing neoplasms, often with clear cell features, in a multitude of organ systems. The most common neoplasms are cerebellar and retinal hemangioblastomas, adrenal pheochromocytomas, clear cell renal cell carcinomas, pancreatic neuroendocrine tumors, pancreatic serous cystadenomas, and endolymphatic sac tumors...

Heterozygous mutations in the gene that encodes the transcription factor hepatocyte nuclear factor 1β (HNF1B) result in a multi-system disorder. HNF1B was initially discovered as a monogenic diabetes gene; however, renal cysts are the most frequently detected feature. Other clinical features include pancreatic hypoplasia and exocrine insufficiency, genital tract malformations, abnormal liver function, cholestasis and early-onset gout. Heterozygous mutations and complete gene deletions in HNF1B each account for approximately 50% of all cases of HNF1B-associated disease and may show autosomal dominant inheritance or arise spontaneously...

OBJECTIVES: This study evaluated individual risks of malignancy and proposed a nomogram for predicting malignancy of branch duct type intraductal papillary mucinous neoplasms (BD-IPMNs) using the large database for IPMN. BACKGROUND: Although consensus guidelines list several malignancy predicting factors in patients with BD-IPMN, those variables have different predictability and individual quantitative prediction of malignancy risk is limited. METHODS: Clinicopathological factors predictive of malignancy were retrospectively analyzed in 2525 patients with biopsy proven BD-IPMN at 22 tertiary hospitals in Korea and Japan...

INTRODUCTION: Hydatid cyst, which is caused by Echinococcus granulosus, is mostly seen in the liver and lungs although it may also rarely be found in any organ or soft tissue. This study presents an interesting case of pancreatic hydatid cyst in which the pancreatic duct opened into this cyst. CASE REPORT: A 10-year-old boy presented to our clinic with significant abdominal distension and pain in the epigastric region which had started 10 days previously. Serum amylase level was 3709 U/L and hemagglutination inhibition for hydatid disease was 1/160...

OBJECTIVE: To investigate using quantitative imaging to assess the malignant potential of intraductal papillary mucinous neoplasms (IPMNs) in the pancreas. BACKGROUND: Pancreatic cysts are identified in over 2% of the population and a subset of these, including intraductal papillary mucinous neoplasms (IPMNs), represent pre-malignant lesions. Unfortunately, clinicians cannot accurately predict which of these lesions are likely to progress to pancreatic ductal adenocarcinoma (PDAC)...

BACKGROUND AND AIMS: Endoscopic ultrasound (EUS) is widely used to evaluate pancreatic cysts. Recent American Gastroenterological Association (AGA) guideline limits EUS for evaluation of cysts with at-least two high-risk features (size ≥ 3 cm, dilated main pancreatic duct or presence of a solid component). We have investigated the impact of this guideline on sensitivity of EUS for pancreatic cancer and the reduction of EUS procedures for pancreas cysts. METHODS: EUS procedures performed between 2004 and 2015 and related patient records were retrospectively reviewed to determine the presence or absence of high-risk features, and for the results of fine needle aspiration cytology...
