A 79-year-old Indian male was admitted with upper abdominal discomfort of 1-year duration which was associated with loss of weight and appetite. Serum tumor markers, including carcinoembryonic antigen and carbohydrate antigen 19-9, were within normal limits. A computed tomographic scan demonstrated a cystically dilated and tortuous pancreatic duct measuring 1.9 cm, suggestive of an intraductal ...
The cell of origin of pancreatic ductal adenocarcinoma (PDAC) has been controversial. Here, we show that identical oncogenic drivers trigger PDAC originating from both ductal and acinar cells with similar histology but with distinct pathophysiology and marker expression dependent on cell of origin. Whereas acinar-derived tumors exhibited low AGR2 expression and were preceded by pancreatic intra...
Serous cystic neoplasms of the pancreas are rare exocrine pancreatic neoplasms, most of which are benign and do not communicate with the pancreatic duct. Pancreatic intraepithelial neoplasm (PanIN) is considered a precursor of ductal adenocarcinoma that is microscopically recognized in pancreatic ducts. A 67-year-old Japanese woman presented with a 10-mm multilocular cystic lesion at the pancre...
Pancreatic cystic lesions are commonly encountered today with the routine use of cross-sectional imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). The majority of patients discovered to have a pancreatic cyst are completely asymptomatic; yet the presence of such a finding instills fear in the minds of both patient and physician, as the concern for maligna...
Complications associated with intraductal papillary mucinous neoplasms, such as acute pancreatitis, perforation, and fistula formation, have been documented. Intraductal papillary mucinous neoplasm with intratumoral hemorrhage is rare. To the best of our knowledge, there have been no previous reports of intraductal papillary mucinous neoplasm rupture and bleeding with intra-abdominal hemorrhage...
CONTEXT Endoscopic ultrasound (EUS) with EUS-guided fine needle aspiration (EUS-FNA) has been increasingly utilized to differentiate malignant/pre-malignant pancreatic cysts from those that are benign or have low malignant potential. OBJECTIVE To determine the utility of EUS morphology, EUS-FNA cytology and cyst fluid analysis to distinguish mucinous cystic neoplasms from non-mucinous cystic ...
Objective Pancreatic ductal adenocarcinoma has a five year survival rate of 20% following radical surgical resection. The aggressive tumor biology and heterogenous nature of pancreatic ductal adenocarcinoma results in metastatic spread which further decreases overall survival. We report a patient who successfully underwent a pulmonary metastasectomy five years after the resection of a pancreati...
