BACKGROUND: Mucinous cystic neoplasms (MCNs) of the pancreas present a management conundrum. The majority are benign but all are resected due to their malignant potential. Recent studies have recommended nonsurgical management. In the current study, the authors analyzed the preoperative imaging, cytology, and cyst fluid characteristics of 136 histologically confirmed MCNs to assess predictors of a high-risk (HR) cyst for surgical triage. METHODS: MCNs resected at the Massachusetts General Hospital between 1990 and 2014 formed the study cohort...

Although the pancreas is affected by only a small fraction of known inherited disorders, several of these syndromes predispose patients to pancreatic adenocarcinoma, a cancer that has a consistently dismal prognosis. Still other syndromes are associated with neuroendocrine tumors, benign cysts, or recurrent pancreatitis. Because of the variability of pancreatic manifestations and outcomes, it is important for clinicians to be familiar with several well-described genetic disorders to ensure that patients are followed appropriately...

Pancreatic cysts are extremely common, and are identified in between 2% to 13% on abdominal imaging studies. Most pancreatic cysts are pseudocysts, serous cystic neoplasms, mucinous cystic neoplasms, or intraductal papillary mucinous neoplasms. The management of pancreatic cysts depends on whether a cyst is benign, has malignant potential, or harbors high-grade dysplasia or invasive carcinoma. The diagnosis of pancreatic cysts, and assessment of risk of malignant transformation, incorporates clinical history, computed tomography (CT), magnetic resonance imaging (MRI), endoscopic ultrasound, and fine-needle aspiration of cyst fluid...

Pancreatic cytopathology, particularly through the use of endoscopic ultrasound-guided fine-needle aspiration (FNA), has excellent specificity and sensitivity for the diagnosis of pancreatic lesions. Such diagnoses can help guide preoperative management of patients, provide prognostic information, and confirm diagnoses in patients who are not surgical candidates. Furthermore, FNA can be used to obtain cyst fluid for ancillary tests that can improve the diagnosis of cystic lesions. In this article, we describe the cytomorphological features and differential diagnoses of the most commonly encountered pancreatic lesions on FNA...

Haemoperitoneum in women of reproductive age usually suggests either ruptured ectopic pregnancy or ruptured ovarian cysts. Metastatic choriocarcinoma is considered the least common cause of haemoperitoneum in women of childbearing age. We report a rare case of pancreatic and hepatic metastasis of choriocarcinoma in a young, 30-year-old female who had delivered 10 months prior at term gestation with no previous history of gestational trophoblastic disease or molar pregnancy. She had a short history of fever and pain in the right hypochondrium, with findings of hypovolaemic shock due to intraperitoneal haemorrhage...

A 53-year-old male visited his primary physician for epigastric and back pain. Abdominal-enhanced computed tomography (CT) revealed a simple cyst of the pancreatic tail attached to the stomach. A distal main pancreatic duct (MPD) was clearly dilated, but no pancreatic tumor was identified around the stenosis of MPD by CT scan and magnetic resonance cholangiopancreatography (MRCP). Endoscopic retrograde pancreatography (ERP) revealed stenosis and distal dilation of the MPD located between the body and tail of the pancreas...

PURPOSE: To evaluate whole-lesion ADC histogram metrics for assessing the malignant potential of pancreatic intraductal papillary mucinous neoplasms (IPMNs), including in comparison with conventional MRI features. METHODS: Eighteen branch-duct IPMNs underwent MRI with DWI prior to resection (n = 16) or FNA (n = 2). A blinded radiologist placed 3D volumes-of-interest on the entire IPMN on the ADC map, from which whole-lesion histogram metrics were generated. The reader also assessed IPMN size, mural nodularity, and adjacent main-duct dilation...

OBJECTIVES: Pancreatic serous cystadenomas (SCAs) are benign tumors. Technological advances in imaging have led to increased recognition of asymptomatic pancreatic cysts, consequently increasing the demand for cytomorphologic evaluations of cyst fluid. STUDY DESIGN: A retrospective search through the pathology archives over an 11-year period was performed to identify SCAs from pancreatectomy specimens with a presurgical pancreatic EUS-guided fine-needle aspiration (FNA)...

BACKGROUND: Incidental small pancreatic cystic lesions (PCLs) are often found on pre-operative imaging in patients undergoing orthotropic liver transplantation (OLT).While these are considered benign or of low malignant potential, the influence of immunosuppression after OLT may be of concern. The aim of this study was to observe the long term outcome of these small pancreatic cystic lesions (PCLs) in post OLT patients. METHODS: An institutional OLT database of 1,778 consecutive OLT patients from January 2000 to December 2010 was analyzed...

Bullous pemphigoid (BP) is an acquired, autoimmune, subepidermal blistering disorder. A possible paraneoplastic association has been suggested; however, debate remains regarding the precise relationship of these neoplasms with BP. We present a case of recalcitrant BP in a 67-year-old man with a pancreatic neoplasm that was found to be a lymphoepithelial cyst. Immunoperoxidase staining of the cyst demonstrated C3d along the basement membrane of the stratified squamous epithelium, suggesting that the BP may have involved the lymphoepithelial cyst itself...

Epithelial cyst in an intrapancreatic accessory spleen (ECIPAS) is exceedingly rare with only 57 cases reported since the first publication in 1980. Comprehensive clinical and diagnostic features remain to be clarified. We present a case of ECIPAS in a 21-year-old Philippine woman who was admitted with right upper quadrant abdominal pain. A cystic lesion in the pancreatic tail was discovered and evaluated by computed tomography and magnetic resonance images. Based on clinical and radiological features a solid pseudopapillary neoplasm was suspected...

Lymphoepithelial cysts (LECs) of the pancreas are benign, rare pancreatic cysts that are found predominantly in men. These cysts can present as a diagnostic conundrum given their rarity and difficulty of distinguishing these cysts from those with malignant potential. We present an incidental case of a LEC in a middle-aged man.

OBJECTIVES: The aim of this study was to compare the prevalence of cystic pancreatic lesions and their natural behavior in 2 distinct high-risk groups for developing pancreatic ductal adenocarcinoma (PDAC): (1) carriers of a mutation that predisposes to PDAC and (2) individuals without a known gene mutation but with a family history of PDAC (familial pancreatic cancer [FPC]). METHODS: Pancreatic surveillance by annual magnetic resonance imaging and endoscopic ultrasound was performed in individuals with an estimated lifetime risk of developing PDAC of 10% or greater...

BACKGROUND: Surgery for pancreatic branch-duct intraductal papillary mucinous neoplasm (BDIPMN) is indicated for therapy of symptomatic patients and to prevent development of invasive cancer. There is currently no consensus on management of BD-IPMN patients after surgical resection. The aim of this retrospective multicenter study was to determine the recurrence and long-term survival after surgical resection of BD-IPMN and to determine the predictive factors of recurrence. METHODS: All patients who underwent surgery for BD-IPMN from 2005 to 2011 at 2 centers were identified...

: Choledochal cyst is a rare pathological condition, which represents 1% of benign diseases of the biliary tract. It is seen with significant frequency in childhood, with a higher prevalence in females, and a greater diagnostic incidence in Asia. Diagnosis is primarily based on clinical suspicion. Its symptoms are variable, and its treatment, depending on the type, is surgical. CASE REPORT: a male patient, 46 years old, with clinical symptoms of acute pancreatitis as a complication of a choledochal cyst Todani type II is diagnosed during his hospital stay with cholangial magnetic resonance...

Acute obstructive suppurative pancreatic ductitis (AOSPD) is a rare clinical entity defined as suppuration from the pancreatic duct without concomitant pancreatic cyst, abscess, or necrosis. We describe a case of AOSPD in a woman with a past medical history of type 2 diabetes and chronic pancreatitis who presented with abdominal sepsis, which resolved only after therapeutic endoscopic retrograde cholangiopancreatography. Our case highlights the importance of considering AOSPD as a cause of abdominal sepsis particularly in patients with chronic pancreatitis or any recent pancreatic duct instrumentation and demonstrates that treatment requires prompt drainage and decompression of the pancreatic duct...

Epidermoid cysts presenting within an intrapancreatic accessory spleen are rare non-neoplastic cysts typically occurring in the pancreatic tail. This entity is difficult to diagnose given there are many types of pancreatic neoplastic cysts. We herein describe two cases of an epidermoid cyst within an intrapancreatic accessory spleen for which we performed a resection by laparoscopic distal pancreatectomy. Epidermoid cysts in an intrapancreatic accessory spleen should therefore be considered in the differential diagnosis of pancreatic tail cystic lesions...

Genetic diseases associated with defects in primary cilia are classified as ciliopathies. Pancreatic lesions and ductal cysts are found in patients with ciliopathic polycystic kidney diseases suggesting a close connection between pancreatic defects and primary cilia. Here we investigate the role of two genes whose deletion is known to cause primary cilium defects, namely Hnf6 and Lkb1, in pancreatic ductal homeostasis. We find that mice with postnatal duct-specific deletion of Hnf6 or Lkb1 show duct dilations...
