Mucinous cystic neoplasms (MCNs) occur in the ovary, pancreas and retroperitoneum but very rarely in the liver. MCNs are known to harbor ovarian-like mesenchymal stroma (OLS) expressing progesterone- and estrogen receptors. In this study we evaluated steroidogenesis in OLS of 25 hepatic MCNs and 24 pancreatic MCNs. Both steroid receptors and steroidogenic factors were immunohistochemically evaluated using H-score and results were compared with those in 15 ovarian MCNs and 10 normal ovaries. Androgen receptor (AR) H-scores in OLS were significantly higher in hepatic, pancreatic and ovarian MCN than those in normal ovaries...

BACKGROUND: Anaplastic carcinoma of the pancreas is a rare pancreatic neoplasm with a poor prognosis. It is classified as a variant of ductal adenocarcinoma, but the clinical features and treatment of it remain unknown because of its rarity and aggressiveness. Endoscopic ultrasonography and endoscopic ultrasound-guided fine-needle aspiration are useful techniques for the diagnosis of pancreatic tumors with high sensitivity and specificity. CASE PRESENTATION: A 72-year-old Japanese woman presented with a diagnosis of acute pancreatitis, and a cystic lesion with slightly high density area was observed by computed tomography in her pancreatic head...

BACKGROUND: The risk of invasive cancer in resected intraductal papillary mucinous neoplasm with main pancreatic duct involvement is 33%-60%. Most guidelines, therefore, advise resection of main duct intraductal papillary mucinous neoplasm and mixed type intraductal papillary mucinous neoplasm in surgically fit patients, although advice on the surgical strategy (partial or total pancreatectomy) differs. We performed a survey amongst international experts to guide the design of future studies and help to prepare for a single international set of guidelines...

Joseph Clarence Torres, Chen Xin
BACKGROUND: Desmoid-type fibromatoses are rare benign and fibrous tumors that account for approximately 0.03% of total neoplasms. Within this category of neoplasms, pancreatic desmoid-type fibromatosis is an extremely rare subgroup, accounting for approximately 5% of desmoid-type fibromatoses. Although the etiology is unknown, some risk factors include trauma, surgery, family history of desmoid tumor, pregnancy, use of contraceptives, genetic mutation, and familial adenomatous polyposis or Gardner syndrome...

Solid pseudopapillary tumour (SPT) is one of the uncommon benign cystic neoplasms of pancreas occurring predominantly in young females. Being benign in nature, surgical resection is the treatment of choice with excellent 5-year survival. A 14-year-old girl presented with pain abdomen for 1 week. On evaluation, she was found to have a large SPT involving head and uncinate process of Pancreas She underwent robotic pylorus preserving pancreaticoduodenectomy (R-PPPD) with da Vinci® Si Robotic System (Intuitive Surgical, Sunnyvale, CA, USA)...

Serous cystadenoma of the pancreas is a common cystic neoplasm typically of benign evolution that rarely communicates with the pancreatic ductal system. We present several images originating from two cases of serous cystadenoma of the pancreas which led to compression and dilatation of Wirsung's duct. These cases suggest that when the diagnosis of pancreatic microcystic lesion is detected, associated, or not associated with a central fibrous scar and a low carcinoembryonic antigen level in the aspirated fluid, the presence of dilatation of Wirsung's duct does not exclude the diagnosis of serous pancreatic cystadenoma...

Purpose: Noninvasive precursor lesions for pancreatic adenocarcinoma include pancreatic intraepithelial neoplasia (PanIN), intraductal papillary mucinous neoplasm, and mucinous cystic neoplasm. PanIN is often found synchronously adjacent to resected pancreatic ductal adenocarcinoma (PDAC) tumors. However, its prognostic significance on outcome after PDAC resection is unknown. The purpose of the current study was to determine if the presence of PanIN has a prognostic or predictive effect on survival after resection for PDAC with curative intent...

Background & Aims: Tissue hypoxia controls cell differentiation in the embryonic pancreas, and promotes tumor growth in pancreatic cancer. The cellular response to hypoxia is controlled by the hypoxia-inducible factor (HIF) proteins, including HIF2α. Previous studies of HIF action in the pancreas have relied on loss-of-function mouse models, and the effects of HIF2α expression in the pancreas have remained undefined. Methods: We developed several transgenic mouse models based on the expression of an oxygen-stable form of HIF2α, or indirect stabilization of HIF proteins though deletion of von Hippel-Lindau, thus preventing HIF degradation...

BACKGROUND: Since the concept of intraductal tubulopapillary neoplasm (ITPN) was introduced in the current World Health Organization classification of tumors, the number of reports of ITPN occurrence has increased gradually. However, ITPN is usually located in the main pancreatic duct, with few reports of a branch duct ITPN. As a result, imaging protocols for the diagnosis of a branch duct ITPN have not been established. CASE PRESENTATION: We report a case of a concurrent presentation of a branch duct ITPN and intraductal papillary mucinous neoplasm (IPMN) in the head of the pancreas, with a superior mesenteric artery (SMA) aneurysm...

Pancreatic ductal adenocarcinoma (PDA) has a 5-year survival rate of less than 5% and is the sixth leading cause of cancer death. Although KRAS mutations are one of the major driver mutations in PDA, KRAS mutation alone is not sufficient to induce invasive pancreatic cancer in mice model. HER2, also known as ERBB2, is a receptor tyrosine kinase, and overexpression of HER2 is associated with poor clinical outcomes in pancreatic cancer. However, no report has shown whether HER2 and its downstream signaling contributes to the pancreatic cancer development...

Simultaneous presence of pancreatic serous cystic neoplasms and neuroendocrine neoplasms is rare. We present a case with the incidental finding of a duodenal neuroendocrine tumor (NET) with 2 lymph node metastases in a Whipple resection specimen performed to remove a pancreatic cystic neoplasm that postoperatively turned out to represent a serous cystic neoplasm (SCN). The patient was a 75-year-old female. She presented with loss of appetite and weight. Preoperative contrast-enhanced computed tomography scan of the abdomen showed a multicystic lesion in the head of pancreas...

This is a case of an epidermoid cyst in an intrapancreatic accessory spleen at the tail of the pancreas. Concurrent epidermoid cyst within the accessory spleen is an exceedingly rare entity. The patient initially presented with abdominal pain, nausea and vomiting. Imaging studies revealed a 3.6 cm cystic mass in the tail of the pancreas that was concerning for a mucinous cystic neoplasm (MCN). The patient underwent a robotic distal pancreatectomy for a suspected diagnosis of MCN, which following histologically examination was found to be an epidermoid cyst of an intrapancreatic accessory spleen...

An epithelial cyst in an intrapancreatic accessory spleen (ECIAS) is rare. We herein report a case of a patient with ECIAS who underwent laparoscopic surgery. A 57-year-old woman was referred to our hospital because of a pancreatic tail tumor. She was asymptomatic, and a physical examination revealed no remarkable abnormalities. The levels of the tumor marker carbohydrate antigen 19-9 (CA19-9) and s-pancreas-1 antigen (SPan-1) were elevated. Ultrasonography showed a well-defined homogeneous cystic tumor. Computed tomography showed a well-demarcated cystic tumor in the pancreatic tail...

BACKGROUND: Although IPMN are thought to represent a whole-gland disease, segmental resection remains the most frequently performed treatment. We sought to determine the rates, patterns, and predictors of IPMN progression in the pancreatic remnant following segmental resection of noninvasive or microinvasive IPMN. METHODS: A prospectively maintained database was queried to identify all patients who underwent resection of noninvasive or microinvasive IPMN (≤ 10 mm of invasive component) between 1989 and 2015...

Evidence-based guidelines on the management of pancreatic cystic neoplasms (PCN) are lacking. This guideline is a joint initiative of the European Study Group on Cystic Tumours of the Pancreas, United European Gastroenterology, European Pancreatic Club, European-African Hepato-Pancreato-Biliary Association, European Digestive Surgery, and the European Society of Gastrointestinal Endoscopy. It replaces the 2013 European consensus statement guidelines on PCN. European and non-European experts performed systematic reviews and used GRADE methodology to answer relevant clinical questions on nine topics (biomarkers, radiology, endoscopy, intraductal papillary mucinous neoplasm (IPMN), mucinous cystic neoplasm (MCN), serous cystic neoplasm, rare cysts, (neo)adjuvant treatment, and pathology)...

Objective: Cystic lesions of the pancreas have been increasingly recognized. Some lesions exhibit benign behavior, while others have unequivocal malignant potential. Thus, accurate identification of malignancy in patients diagnosed with pancreatic cystic neoplasms (PCNs) remains a major challenge. The aim of this study was to define a combined criterion to better predict malignant lesions in patients with PCNs. Methods: We retrospectively analyzed 165 patients who underwent resection of PCNs from October 2011 to May 2017...

Endoscopic ultrasound is increasingly being used for evaluation of pancreatic diseases and pancreatic tumors. Among various pancreatic cystic lesions, cystic degeneration of pancreatic neuroendocrine neoplasm is of the challenge in making diagnosis. Although unique characteristic of each type of pancreatic cystic lesions has been proposed abundantly, typical morphology of cystic degeneration of pancreatic neuroendocrine neoplasm is still unclear. We, herein, reported a case of 66-year-old woman who was incidentally found to have a cystic lesion in the tail of pancreas upon screening transabdominal ultrasonography...

BACKGROUND: Lymphoepithelial cysts (LECs) are rare pancreatic cystic lesions. Since LECs are benign, preoperative diagnosis is important to differentiate from a cystic neoplasm and avoid unnecessary surgery. The aim of this study was to identify clinical, radiographic and cytopathologic features associated with LECs. METHODS: A retrospective review was performed of patients diagnosed with LEC between 1995 and 2017 at our hospital. Clinicopathologic and radiographic imaging features were documented...

Our purpose was to assess the endoscopic ultrasonography (EUS) features of serous cystic neoplasms (SCNs) of the pancreas in determining the surgical removal compared with computed tomography (CT) and magnetic resonance imaging (MRI) features. For 33 consecutive patients with 34 surgically confirmed SCNs over the past 11 years, preoperative EUS features were compared with those of CT and MRI (CT&MRI). Besides the lesion size and location, a retrospective analysis of the various imaging features was performed by 2 observers to understand the characteristics that determine the need for surgical intervention in terms of multiplicity of locules, calcification, mural thickening, mural nodules, ductal communication, and main pancreatic duct dilatation in addition to the gross morphologic type: microcystic, macrocystic (>1 cm), mixed, or solid...
