Renal and pancreatic cysts and tumors are the most common visceral manifestations of von Hippel-Lindau (VHL) disease, a heritable multisystem cancer syndrome characterized by development of a variety of malignant and benign tumors. We report a case of a VHL patient with multiple renal cystic and complex cystic/solid lesions. The patient underwent Ga-DOTA-TATE-PET/CT showing intensely increased activity by a solid lesion which demonstrated enhancement on both CT and MRI scans, raising high suspicion for malignancy...

BACKGROUND: Serum cancer antigen 19-9 (CA19-9) provides additional information about mucinous cystic pancreatic neoplasm (MPN). This study was undertaken to assess both CA19-9 and carcinoembryonic antigen (CEA) serum concentrations in consecutive patients affected by MPNs and other chronic benign and malignant pancreatic diseases. We also evaluated whether serum CA19-9 and CEA determinations provide additional information such as the presence of invasive carcinoma in MPN patients. METHODS: Serum CA19-9 and CEA from 91 patients with pancreatic diseases were tested by commercially available kits at the time of diagnosis...

Gastrointestinal stromal tumors (GISTs) are mesenchymal neoplasms that arise in the gastrointestinal tract, accounting for ~1% of gastric malignancies. The present study reports the case of a GIST of the stomach in a 75-year-old man who presented with abdominal distension and anorexia for 1 month. Gastroscopy was unremarkable. Ultrasound and computed tomography (CT) scans showed a giant intraabdominal cystic lesion of unknown origin. The lesion was initially believed to be a duplication cyst, a pancreatic pseudocyst or a liver cyst in the pre-operative diagnosis...

BACKGROUND: Beside hepatocellular carcinoma, metastasis, and cholangiocarcinoma, the imaging findings of other relatively uncommon hepatic lesions are less discussed in the literature. Imaging diagnosis of these lesions is a daily challenge. In this article, we review the imaging characteristics of these neoplasms. METHODS: From January 2003 to December 2014, 4746 patients underwent liver biopsy or hepatic surgical resection in our hospital. We reviewed the pathological database retrospectively...

BACKGROUND: The current management of pancreatic mucinous cystic neoplasms (MCN) is defined by the consensus European, International Association of Pancreatology and American College of Gastroenterology guidelines. However, the criterion for surgical resection remains uncertain and differs between these guidelines. Therefore through this systematic review of the existing literature we aimed to better define the natural history and prognosis of these lesions, in order to clarify recommendations for future management...

So far, a fatty pancreas has been related to obesity and the ageing processes in the body. The current list of pathogenetic factors of the condition is clearly extended with genetically conditioned diseases (cystic fibrosis, Shwachman-Diamond syndrome and Johanson-Blizzard syndrome), pancreatitis, especially hereditary and obstructive, metabolic and hormonal disorders (hypertriglyceridemia, hypercholesterolemia, hyperinsulinemia and hypercortisolemia), alcohol overuse, taking some medicines (especially adrenal cortex hormones), disease of the liver and visceral adiposis...

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...

Confocal laser endomicroscopy (CLE) is a novel in vivo imaging technique that can provide real-time optical biopsies in the evaluation of pancreaticobiliary strictures and pancreatic cystic lesions (PCLs), both of which are plagued by low sensitivities of routine evaluation techniques. Compared to pathology alone, CLE is associated with a higher sensitivity and accuracy for the evaluation of indeterminate pancreaticobiliary strictures. CLE has the ability to determine the malignant potential of PCLs. As such, CLE can increase the diagnostic yield of endoscopic retrograde cholangiopancreatography and endoscopic ultrasound, reducing the need for repeat procedures...

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...

It is important to adequately and timely identify individuals with cancer worries amongst participants in a pancreatic ductal adenocarcinoma (PDAC) surveillance program, because they could benefit from psychosocial support to decrease distress. Therefore, the aim of this study was to assess both psychosocial and clinical factors associated with cancer worries. High-risk individuals participating in PDAC-surveillance were invited to annually complete a cancer worry scale (CWS) questionnaire which was sent after counseling by the clinical geneticist (T0), after intake for participation in PDAC-surveillance (T1), and then annually after every MRI and endoscopic ultrasonography (EUS) (T2 and further)...

BACKGROUND: Ethanol, a commonly available agent, has been used to successfully ablate cystic and solid lesions in the pancreas. The aim of this study is to investigate the effects of an ethanol injection into the porcine pancreas and observe the time-dependent image changes in the pancreatic parenchyma. METHODS: Pure ethanol was injected into the pancreatic tail using a 25-gauge EUS needle with direct ultrasound guidance under celiotomy: 1 mL and 2 mL were injected, respectively...

Intraductal oncocytic papillary neoplasms (IOPNs) are cystic neoplasms with intraductal growth and complex papillae composed of oncocytic cells. IOPNs have been reported both in the pancreas and biliary tree, and are most likely closely related in these 2 locations. In the pancreas, these rare tumors are now considered 1 of the 4 histologic subtypes of intraductal papillary mucinous neoplasm (IPMN). Significant differences in histology, immunophenotype, and molecular genetics have been reported between IOPNs and other IPMN subtypes...

Pancreatic cystic lesions can be benign, premalignant or malignant. The recent increase in detection and tremendous clinical variability of pancreatic cysts has presented a significant therapeutic challenge to physicians. Mucinous cystic neoplasms are of particular interest given their known malignant potential. This review article provides a brief but comprehensive review of premalignant pancreatic cystic lesions with advanced endoscopic ultrasound (EUS) management approaches. A comprehensive literature search was performed using PubMed, Cochrane, OVID and EMBASE databases...
