CONTEXT The pancreas is formed by ventral and dorsal pancreatic buds which arise from the endodermal lining of the gut. When the duodenum rotates to the right, the ventral pancreatic bud migrates dorsally and finally come and lie below the dorsal pancreatic bud. The developmental errors in the rotation of these components lead to annular pancreas. CASE REPORT We report a rare type of the inco...

Heterotopic pancreatic tissue of the stomach is a rare condition. The author herein reports three cases of heterotopic pancreatic of the stomach. The three cases were found in the 8,154 gastric specimens (biopsy 6,122 cases, gastrectomy 2,032 cases) of our pathology laboratory; the frequency was 0.04%. The first case was a 57-year-old woman who presented with epigastralgia. Endoscopic examinati...

BACKGROUND Pancreas divisum, the most common congenital anomaly of the pancreas, is caused by failure of the fusion of the ventral and dorsal pancreatic duct systems during embryological development. Although various pancreatic tumors can occur in patients with pancreas divisum, intraductal papillary mucinous neoplasm is rare. CASE PRESENTATION A 77-year-old woman was referred to our hospital...

Heterotopic, aberrant or ectopic pancreas is defined as the presence of pancreatic tissue in topographic anomaly, with no anatomical, neural or vascular connection to the normal pancreas. It is a rare condition found mainly in stomach, duodenum and jejunum. Ileal heterotopic pancreas is an uncommon condition and has been rarely reported in children so far. Hereby we report a case of heterotopic...

Pancreaticobiliary maljunction (PBM) is a congenital anomaly defined as junction of the pancreatic and bile ducts located outside the duodenal wall beyond the influence of the sphincter of Oddi, usually forming a markedly long common channel. Other names are “anomalous arrangement of pancreaticobiliary ducts” or “anomalous union of biliopancreatic ducts” [1]. Average length of common channel is...

Endoscopic retrograde cholangiopancreatography (ERCP) is nowadays a valuable method for detailed diagnostic evaluation and minimally invasive therapy for biliary and pancreatic diseases in pediatric population. The technique of ERCP is no more difficult in children than in adults, and except infants, there is no need for use a special pediatric endoscope. In children ERCP is usually performed w...

Cystic pancreatic tumors are rare in children and the immature cystic teratoma of the pancreas is even rarer. A review of the world literature shows 18 documented cases involving all the age groups. The preoperative evaluation of this lesion is rather questionable, with definitive diagnosis taking place intraoperatively. We report the 19(th) case, in a 5-month-old male child. The clinical prese...

A Meckel's diverticulum is a remnant of the vitelline duct, which leads to the formation of a true diverticulum containing all layers of the small intestine. The diverticulum can contain ectopic gastric, duodenal or pancreatic tissue and is the most common congenital anomaly of the gastrointestinal tract with estimates of prevalence ranging from 0.3% to 3%. The condition is usually clinically s...

Annular Pancreas (AP) is a rare congenital developmental anomaly which results from failure of the ventral bud to rotate fuse with dorsal bud, resulting in ring pancreatic parenchyma that surrounds second portion duodenum. This entity can be partial or complete and even rarer. Most cases manifest infancy but may remain asymptomatic various nonspecific clinical manifestations are seen adults. We...

We herein demonstrate a case of a gastric-type duplication cyst of the pancreas with a bifid tail in a 1year-old girl, who presented as relapsing pancreatitis with pseudocyst formation. We reviewed the literature concerning pancreatic enteric duplication cysts with and without pancreatitis to search for causes of pancreatitis. The following new information was obtained: 1) The presence of a com...
