Isolated pancreatic tuberculosis (TB) remains a rarity despite the high incidence of tuberculosis in many of the African and Asian countries. Presentation as discrete pancreatic mass often masquerades as pancreatic neoplasm and diagnosis may require histology. Extra-hepatic portal hypertension due to splenic vein thrombosis complicating pancreatic TB has been reported in the literature. We repo...

Pancreatic cancer is strongly associated with diabetes mellitus. About 80% of the patients with pancreatic ductal adenocarcinoma have glycometabolic alterations. On the contrary, patients with new-onset diabetes mellitus within 1-3 years have a significant increased risk of pancreatic neoplasm up to 5-8 folds. Long-standing diabetes increases the risk for pancreatic cancer, while pancreatic can...

CONTEXT Pancreatic heterotopia in itself is rare in the colon and to the best of our knowledge a neoplasm arising in a heterotopic tissue in the colon has not been reported. We herein report a pancreatic cystic neoplasm arising from heterotopic pancreatic tissue in colon. CASE REPORT A 44-year-old lady presented with a history of lower abdominal colic, associated with mucoid loose stools 10-1...

Patients with pancreatic adenocarcinoma are known to have a high mortality rate. The 5-year survival rate still remains low even now compared to that of the 1960's despite new advances in management including surgery, chemotherapy, pathological classification and molecular diagnostic technologies. Precursors to invasive pancreatic adenocarcinoma have been identified in the last ten years that i...

A 69-year-old woman was referred to our hospital after incidental identification of a pancreatic mass during follow-up for diabetes mellitus. Various imaging examinations showed a tumor in the main pancreatic duct, without apparent hypersecretion of mucin. Brush cytologic examination revealed class V disease (adenocarcinoma). Because preoperative examination suggested an intraductal neoplasm wi...

CONTEXT An intraductal oncocytic papillary neoplasm is a rare pancreatic tumor which was first described by Adsay et al. in 1996. It has been defined as a new subgroup of IPMN. CASE REPORT We report the case of a 76-year-old woman who presented with nausea. Imaging studies revealed a cystic mass in the body of the pancreas. She underwent a successful distal pancreatectomy and splenectomy, and...

BACKGROUND AND STUDY AIMS The purpose of this study was to identify possible associated factors that may have contributed to failure to detect a pancreatic neoplasm during endoscopic ultrasound (EUS) examinations by experienced endosonographers. PATIENTS AND METHODS A multicenter retrospective study was organized, and 20 cases of pancreatic neoplasms missed by nine experienced endosonographer...

CT: computed tomography EUS: endoscopic ultrasound scan IPMN: intraductal papillary mucinous neoplasm MRCP: magnetic resonance cholangiopancreatography MPD: main pancreatic duct INTRODUCTION Pancreatic panniculitis is a rare skin manifestation of pancreatic disease. It is believed to result from seepage of pancreatic enzymes into the systemic circulation, which leads to skin and occasionally jo...
