Most pancreatic ductal adenocarcinomas (PDAs) show solid growth pattern, but ductal adenocarcinomas may demonstrate intratumoral cystic appearance or accompany peritumoral non-neoplastic cystic lesions, thus mimicking cystic pancreatic tumors on imaging studies. The histopathologic findings for PDA with cystic feature are divided into neoplastic and non-neoplastic cysts. Neoplastic cystic changes include large-duct type cysts (microcystic appearance), neoplastic mucin cysts (macrocystic appearance), colloid carcinomas (mucinous noncystic adenocarcinomas), and degenerative cystic change usually caused by hemorrhagic necrosis of tumor...

Cystic lesions of the pancreas are radiographic findings that have a very broad histologic differential. This differential spans the spectrum from benign to cancerous, and includes non-neoplastic pseudocysts, benign neoplastic cysts, pre-malignant cysts, and cystic lesions with invasive carcinoma. This chapter will highlight the challenges with diagnosis and management of patients who present with cystic neoplasms of the pancreas.

Purpose: Blunt trauma of pancreas in children is uncommon and its management varies from observational to early operative intervention. We analysed the feasibility and outcome of non-operative management in all grades of paediatric pancreatic injuries. Methods: A total of 15 patients of pancreatic trauma seen in a Paediatric Surgery Unit were retrospectively analyzed. Results: Age of the patients ranged from 3-11 years (mean, 7.7 years). The mode of injury was local trauma in 9 children...

Solid pseudopapillary neoplasm (SPN) of the pancreas is considered a low-malignant neoplasm with a good prognosis. However, 5% to 15% of patients with SPNs develop metastatic disease, most commonly in the liver. Metastatic hepatic malignancies that show pseudocystic features are rare. Here we describe the case of a middle-aged female with a cystic liver metastasis from SPN. To the best of our knowledge, SPN with a single cystic liver metastasis has not been described, although these tumours frequently undergo haemorrhagic-cystic degeneration...

RATIONALE: Pancreaticocolonic fistula (PCF) is an exceedingly rare complication of severe acute pancreatitis (SAP) and has primarily been treated surgically, but a few reported cases are successfully treated with nonsurgical methods. PATIENT CONCERNS: A 32-year-old male presented to our hospital with chief complaints of sharp and persistent left upper quadrant abdominal pain radiating to the back. DIAGNOSES: Computed tomography showed a pancreatic pseudocyst replacing a majority of the pancreatic parenchyma and PCF that formed between the pancreas and the colon...

Cystic pancreatic tumors account for 10% of cystic lesions in the pancreas. Evaluation focuses on identifying lesions that require surgical resection due to actual or potential malignancy. Cystic tumors with malignant potential include mucinous cystic neoplasms (MCN), intraductal papillary mucinous neoplasm (IPMN), and cystic neuroendocrine tumors. The sensitivity of endoscopic fine-needle aspiration (FNA) to diagnose such lesions is low and a more accurate marker of malignant potential is needed. Aldo-keto reductase 1B10 (AKR1B10) was originally found in human hepatocellular carcinoma...

Pancreatic pseudocyst is a common complication of acute pancreatitis. Pseudocysts are commonly observed in the lesser sac and retroperitoneum; they are rarely seen in the liver. Herein, we report a case of intrahepatic pseudocyst, complicated by asymptomatic groove pancreatitis, that has successfully been treated with hepatic resection. A 70-year-old woman was referred to our hospital with severe upper abdominal pain. Abdominal computed tomography scan showed 11x10 cm sized cystic lesion in the left lateral section of the liver...

Literature on the behavior of cystic lesions in pancreas transplants is scarce, and hence a better understanding is warranted. Data on recipients and their respective donors that underwent simultaneous kidney and pancreas, pancreas transplant alone, and pancreas after kidney between 1994-2015 were reviewed (n=1185). Cystic lesions of the transplant pancreas developed in 22 patients (1.8%): 12 pseudocysts, 2 cysts/remnants, 4 intraductal papillary mucinous neoplasms (IPMN), 2 adenocarcinomas, 1 low grade intraepithelial pancreatic neoplasia, and 1 case of polycystic kidney disease...

Heterotopic pancreas (HP) is a relatively uncommon entity that is defined as pancreatic tissue without a true anatomical or vascular connection to the pancreas. HP does not cause symptoms in most cases but can occasionally produce various manifestations, including nausea, vomiting, abdominal pain, and even heterotopic pancreatitis. Here, we report an unusual case in which heterotopic pancreatitis complicated by the formation of a pseudocyst that caused gastric outlet obstruction was diagnosed based on serum hyperamylasemia and findings from endoscopic ultrasonography (EUS)-guided fine needle aspiration (EUS-FNA) cytology...

Chronic pancreatitis is defined as a pathological fibro-inflammatory syndrome of the pancreas in individuals with genetic, environmental and/or other risk factors who develop persistent pathological responses to parenchymal injury or stress. Potential causes can include toxic factors (such as alcohol or smoking), metabolic abnormalities, idiopathic mechanisms, genetics, autoimmune responses and obstructive mechanisms. The pathophysiology of chronic pancreatitis is fairly complex and includes acinar cell injury, acinar stress responses, duct dysfunction, persistent or altered inflammation, and/or neuro-immune crosstalk, but these mechanisms are not completely understood...

Pseudoaneurysm of peripancreatic vessel is a rare complication of pancreatitis. The splenic artery is the most commonly affected vessels close to the pancreas. Pseudoaneurysm of right gastroepiploic artery is rare. It can rupture into Gastro Intestinal (GI) tract, retroperitoneum, peritoneal cavity, biliopancreatic duct or pseudocyst. Clinical diagnosis of unruptured pseudoaneurysm is rarely possible because there are no specific signs and symptoms. We hereby report a case of pseudoaneurysm of aberrant right gastroepiploic artery in 30-year-old male which presented with history of epigastric pain and lump with episode of haematemesis and malena...

During routine dissection, duplication of main pancreatic duct extending from body to head region of pancreas was observed in a 78-year-old formalin fixed male cadaver. Main pancreatic duct gave a prominent branch which joined back the parent duct in head resulting in the formation of a closed loop. This gave the appearance of focal duplication in the form of a closed loop, an unusual variant. This was an incidental finding. Such cases usually remain asymptomatic; however, if undetected may be the cause of postoperative pancreatic fistula following pancreaticobiliary surgery...

Postinflammatory pancreatic pseudocysts are one of the most common complications of acute pancreatitis. In most cases, pseudocysts self-absorb in the course of treatment of pancreatitis. In some patients, pancreatic pseudocysts are symptomatic and cause pain, problems with gastrointestinal transit, and other complications. In such cases, drainage or resection should be performed. Among the invasive methods, mini invasive procedures like endoscopic transmural drainage through the wall of the stomach or duodenum play an important role...

Although hydatid cysts are often seen in the liver and lungs, they may be present in many organs. Even in countries where hydatid cyst disease is endemic, the occurrence of pancreatic hydatid cysts is rare. Pancreatic hydatid cysts are important for the differential diagnosis of patients with pancreatic pseudocysts and cystic carcinomas. We could not find cystic echinococcosis cases which are kept together pancreas and liver in PubMed. In this article, we highlight the fact that pancreatic cystic echinococcosis may play a role in the etiology of cholestasis and that cysts may not be isolated in the pancreas in a pediatric population...

BACKGROUND: Pancreatic pseudocyst (PP) is the commonest cystic lesion of the pancreas. Internal drainage of PPs can be accomplished by traditional open or recently by minimally invasive laparoscopic or endoscopic approaches. We aimed to evaluate and compare the clinical outcomes after endoscopic, laparoscopic, and open drainage. METHODS: Seventy-one patients with PP underwent endoscopic (n = 35), laparoscopic (n = 4), and open surgical drainage (n = 32)...
