Primary pancreatic carcinosarcoma is a rare and malignant neoplasm arising within the pancreas. With fewer than a dozen cases ever reported, the recognition and treatment of this rare phenomenon can be difficult. We describe the case of an 85-year-old man who presented with vague right upper quadrant and epigastric abdominal pain and was found to have a pancreatic mass on ultrasound and computed tomography. The patient underwent open pancreaticoduodenectomy and was found to have pancreatic carcinosarcoma on microscopic evaluation...

Pancreatic hydatid cysts are fairly rare. The disease can be encountered concurrently with systemic involvement or as an isolated pancreatic involvement. We report the first case of spleen-preserving laparoscopic distal pancreatectomy for a pancreatic hydatid cyst. There was no complication or recurrence. A 55-year-old woman was admitted to our centre with epigastric and back pain. Upper abdominal magnetic resonance imaging revealed a solitary cystic lesion with septations at the pancreatic tail level measuring 24 mm × 18 mm, which was initially thought to be a pancreatic mucinous cystic neoplasia...

Xanthogranulomatous inflammation of the pancreas is an extremely rare entity mimicking pancreatic neoplasia. Elevation of tumor markers has seldom been reported in xanthogranulomatous inflammation of the pancreas, rendering the diagnosis difficult and highlighting the importance of a meticulous histopathological examination. A 58-year-old male presented with severe abdominal pain and anorexia for six months. A heterogeneously enhancing solid cystic mass was detected in the pancreatic head on contrast enhanced computed tomography...

OBJECTIVE: We sought to identify clinicopathological characteristics of high-grade pancreatic intraepithelial neoplasia (PanIN)/carcinoma in situ to facilitate screening for pancreatic ductal adenocarcinoma. METHODS: We evaluated PanIN lesions in 173 consecutive autopsy cases with no evidence of pancreatic ductal adenocarcinoma and/or intraductal papillary mucinous neoplasm (mean age, 80.5 years) by submitting the entire pancreas for microscopic examination. RESULTS: PanIN-3 was found in 4% of examined cases, whereas PanIN-1 and PanIN-2 were present in 77% and 28%, respectively...

OBJECTIVES: Pancreatic ductal adenocarcinoma arises from the following 3 distinct precursor lesions: pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasm, and mucinous cystic neoplasm (MCN). Genetic abnormalities in the first 2 precursor lesions have been well characterized, but there are limited data on progression pathways in MCNs. This study aimed to characterize genomic differences between MCNs with low-grade (LG) and high-grade (HG) dysplasia or carcinoma...

Pancreatobiliary tract lesions are increasingly being discovered because of more sensitive imaging modalities. Magnetic resonance imaging has identified incidental pancreatic cysts in 13.5% of patients of progressively increasing age. Pancreatobiliary tissue is more accessible through endoscopic ultrasound and magnetic resonance imaging-guided biopsy procedures, and is now an integral part of pathologists' routine practice. Accordingly, several new tumor categories have been recently recognized, including intraductal tubulopapillary neoplasm, a new addition to tumoral intraepithelial neoplasms...

To better understand pancreatic ductal adenocarcinoma (PDAC) and improve its prognosis, it is essential to understand its origins. This article describes the pathology of the 3 well-established pancreatic cancer precursor lesions: pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasm, and mucinous cystic neoplasm. Each of these precursor lesions has unique clinical findings, gross and microscopic features, and molecular aberrations. This article focuses on histopathologic diagnostic criteria and reporting guidelines...

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...

BACKGROUND & AIMS: Little is known about the origin of pancreatic intraductal papillary mucinous neoplasms (IPMN). Pancreatic duct glands (PDGs) are gland-like outpouches budding off the main pancreatic ducts that function as a progenitor niche for the ductal epithelium; they express gastric mucins and have characteristics of side-branch IPMNs. We investigated whether PDGs are a precursor compartment for IPMNs and the role of Trefoil factor family 2 (TFF2)-a protein expressed by PDGs and the gastric mucosa that are involved in epithelial repair and tumor suppression...

BACKGROUND: In 2015, the American Gastroenterological Association (AGA) published guidelines to provide recommendations for management of suspected pancreatic cystic neoplasms (PCNs). The aim of this study was to compare efficacy of these with the Fukuoka consensus guidelines in predicting advanced neoplasia (AN) in patients with suspected PCNs. STUDY DESIGN: We performed a retrospective study of 239 patients who underwent surgical resection for suspected mucinous PCN at a tertiary care center from 2000 to 2014...

BACKGROUND: Solid pseudopapillary pancreatic neoplasia is usually a large well-circumscribed pancreatic mass, with cystic and solid areas more frequently found in young women. It is a benign pancreatic neoplasia in most cases, therefore minimally invasive surgery could be an interesting approach. AIM: Evaluate the results of minimally invasive surgery for this neoplasia. METHODS: Patients with this tumor who underwent minimally invasive pancreatectomies between 2009 and 2015 in a single institution, were analyzed regarding demographic, clinical-pathological futures, post-operative morbidity and disease-free survival...

Mutational activation of K-Ras is an initiating event of pancreatic ductal adenocarcinomas (PDAC) that may develop either from pancreatic intraepithelial neoplasia (PanIN) or intraductal papillary mucinous neoplasms (IPMN). Cyclooxygenase-2 (COX-2)-derived prostaglandin E2 (PGE2) is causally related to pancreatic carcinogenesis. Here, we deciphered the impact of COX-2, a key modulator of inflammation, in concert with active mutant K-Ras(G12D) on tumor burden and gene expression signature using compound mutant mouse lines...

Although a mucinous nonneoplastic cyst (MNNC) of the pancreas is defined as a benign nonneoplastic lesion with no malignant potential, its histogenesis and etiology are still uncertain. To explore the origin and development of MNNC, we searched for neoplasia-associated mutational change in oncogene and tumor suppressor genes. Specifically, we analyzed KRAS oncogene mutations by polymerase chain reaction/dideoxy DNA (Sanger) sequencing and tumor suppression gene deletion by loss of heterozygosity (LOH) using polymerase chain reaction/capillary gel electrophoresis for a panel of 16 polymorphic microsatellite repeat markers targeting common tumor suppression gene loci at 1p, 3p, 5q, 9p, 10q, 17p, 17q, 18q, 21q, and 22q on DNA isolated from the cystic lining epithelium microdissected from 15 surgically diagnosed MNNCs by microdissection of unstained histologic sections of fixed resection specimens...

OBJECTIVE: Surveillance programmes are recommended for individuals at risk (IAR) of familial pancreatic cancer (FPC) to detect early pancreatic cancer (pancreatic ductal adenocarcinoma, PDAC). However, the age to begin screening and the optimal screening protocol remain to be determined. METHODS: IAR from non-CDKN2A FPC families underwent annual screening by MRI with endoscopic ultrasonography (EUS) in board-approved prospective screening programmes at three tertiary referral centres...

Pancreatic cancer has a 5-year survival rate of less than 4%. Despite advances in diagnostic technology, pancreatic cancer continues to be diagnosed at a late and incurable stage. Accurate biomarkers for early diagnosis and to predict treatment response are urgently needed. Since alteration of glucose metabolism is one of the hallmarks of cancer cells, we proposed that pyruvate kinase type M2 (M2PK) and lactate dehydrogenase A (LDHA) enzymes could represent novel diagnostic markers and potential therapeutic targets in pancreatic cancer...

Intraductal papillary mucinous neoplasia (IPMN) is one of the cystic neoplasias of the pancreas. The imaging findings provide that these tumors are differentiated from the other cystic lesions of the pancreas, especially from the chronic pancreatitis, where the treatment protocol is completely different. Therefore, the correct diagnosis and classification of the IPMN ensures that the patient receives the correct approach and the appropriate surgery, if necessary. The purpose of this study is to emphasize the imaging findings of the different types of the IPMN and the changes in the management protocol of the patients according to these radiological findings...

Periampullary region encircles a radius of 2 cm around the ampulla of Vater; accordingly, four distinct neoplasias with overlapping imaging features originate in the region. Each of these lesions has a different long-term prognosis; hence, imaging evaluation to characterize the lesion is important. Further certain specific features pertaining to the vascular invasion and systemic spread may decide about the treatment as well as surgical approach. An understanding of the advances in imaging and image processing technology as well as in the methods of image acquisition, for the purpose, is quite relevant towards etching out a rational pre-treatment evaluation protocol...
