Ectopic pancreas is a relatively common congenital anomaly and is usually asymptomatic. Pancreatitis in the ectopic site and pseudocyst formation is extremely rare. To date, only 2 cases have been reported. We present a case of a 3-year-old girl with recurrent pancreatitis and unilateral hydronephrosis of the horseshoe kidney, which was produced by pancreatic pseudocyst arising from ectopic pancreas and isolated intestinal duplication in mesocolon. This is the first case of pancreatic pseudocyst that expanded to the retroperitoneal space and caused urinary tract obstruction.

Ectopic pancreas (EP) is the relatively uncommon presence of pancreatic tissue outside the normal location of the pancreas. This condition is usually asymptomatic and rarely complicated by pancreatitis and malignant transformation. A few cases of neoplastic phenomena that developed from EP into the duodenal wall are described in the literature. Herein we report a case of gastric outlet obstruction due to adenocarcinoma arising from EP of the duodenal wall. The patient underwent a Whipple's procedure and had an uneventful post-operative recovery. Traditional imaging studies are often inconclusive in the definitive diagnosis, whilst endoscopic ultrasonography and guided biopsy may aid accurate pre-operative diagnosis. Diagnostic uncertainty warrants surgical exploration and if necessary extended resection is indicated.

Ectopic pancreas is defined by the presence of abnormally situated pancreatic tissue that lacks contact with normal pancreas and possesses its own duct system and vascular supply. Ectopic pancreas in the gastrointestinal tract is not uncommon. Moreover, there are several reported cases of adult ectopic pancreatitis in the literature, but to date, only two cases of pediatric ectopic pancreatitis have been reported. We describe a 15-year-old female with acute right upper quadrant pain and elevated serum lipase and amylase, in whom the radiological diagnosis was mesenteric soft tissue mass with adjacent inflammatory changes. The surgical pathology diagnosis, however, was mesenteric ectopic pancreas complicated by pancreatitis. We advocate for ectopic pancreatitis to be considered in a pediatric patient with acute abdominal pain, laboratory findings consistent with pancreatitis, and imaging findings of a mesenteric mass and normal orthotopic pancreas.

Ectopic pancreas in the gallbladder is found very rarely in histological examination after cholecystectomy. The etiology of this entity is not yet clear, but there exist several hypotheses about its origin. Our histological study revealed both exocrine and endocrine components of pancreatic tissue as shown by H&E and immunohistochemical staining of a gallbladder sections of a 55-year old man. Ectopic pancreatic tissue may be an underestimated cause of acute idiopathic pancreatitis thus detailed postoperative histological examination may decrease the number of acute pancreatitis cases without the known cause.

Ectopic pancreas rarely causes symptoms or complications. We analyzed 2 atypical cases of ectopic pancreas associated with acute ectopic pancreatitis, 1 of which was induced by endoscopic ultrasound with fine-needle aspiration (EUS-FNA). The patients were seen at a tertiary medical center where they had undergone computed tomography, esophagogastroduodenoscopy, and EUS-FNA analyses. They initially received conservative medical treatment and were later treated by surgery. Both patients were diagnosed with ectopic pancreas of the stomach on the basis of computed tomography, esophagogastroduodenoscopy, or EUS-FNA. Surgical resection cured both patients and confirmed the diagnosis of ectopic pancreas. Acute ectopic pancreatitis is an unusual complication of ectopic pancreas that can be induced by EUS-FNA and diagnosed and cured with surgery.

Pancreas ectopia / Ectopic pancreas (EP) is a rare congenital disease, most typically diagnosed in asymptomatic patients by incidental detection during surgery or at autopsy. It is defined by the presence of pancreatic tissue localized in various places drifting from the foregut or mesentery. It is subject to the same various inflammatory or neoplastic disorders that may affect the orthotopic pancreas, e.g. pancreatitis or pancreatic tumours. Upper GI endosonography is a key examination (tool) in detecting and defining gastroduodenal ectopic pancreas. However its diagnosis remains difficult. The final diagnosis relies on histopathologic analysis of the resected tumor required to confirm the diagnosis. Its treatment is based on patients' condition and symptoms as well as the kind of surgery depending on the location of the ectopic pancreatic tissue.

Ectopic pancreas is a congenital anomaly and the most common type of ectopic tissue in the gastrointestinal tract. Most patients with an ectopic pancreas are asymptomatic and rarely have complications. Ectopic pancreatitis after an endoscopic biopsy has not been reported. We report a patient who developed acute ectopic pancreatitis in the stomach after an endoscopic biopsy. A 71-year-old male patient presented with a subepithelial tumor (SET) in the stomach and had no symptoms. Endoscopic ultrasonography demonstrated a 30-mm hypoechoic mural mass, lobulated margins, and anechoic duct-like lesions. To obtain proper tissue specimen, endoscopic biopsy was performed through the opening on the surface of the mass. The pathologic results confirmed an ectopic pancreas. One day after the endoscopic biopsy, he developed persistent epigastric pain. His serum amylase and lipase elevated. Computed tomography of the abdomen showed swelling of the SET and diffuse edema of the gastric wall. His condition was diagnosed as acute ectopic pancreatitis occurring after endoscopic biopsy.

An ectopic pancreas, also known as pancreatic rest or heterotopic pancreas, consists of pancreatic tissue found in a location with no continuity with the anatomic pancreas. This lesion can occasionally cause gastrointestinal obstruction, ulceration or become inflamed and cause ectopic pancreatitis. We present the case of a 29-year-old immunocompromised female patient due to a previous kidney transplant. She presented with nausea and vague abdominal discomfort and was admitted for investigation and treatment of an acute kidney injury. A small bowel mass of unknown etiology was incidentally found on abdominal computed tomography imaging. Due to the high suspicion of a post-transplant lymphoproliferative disease, a surgical exploration took place and revealed the presence of a pancreatic rest with chronic pancreatitis. Ectopic pancreas diagnosis is challenging and surgical exploration is warranted when a neoplastic process is suspected.

Ectopic pancreas is uncommon in the anterior mediastinum. Herein, a 32-year-old woman presented to our institution for investigation of an abnormal mediastinal shadow on chest computed tomography. The patient underwent complete surgical resection of the anterior mediastinal mass by right thoracoscopy, and the postoperative pathology examination confirmed the diagnosis of ectopic pancreas. There were no clinical signs of pancreatitis. No recurrence or metastasis was observed during a follow-up period of 3 years. English language medical literature was also searched in order to identify other case reports describing this rare condition and identified 17 papers describing 20 cases of anterior mediastinal ectopic pancreas, which were all confirmed at surgery. All clinical characteristics in these cases were reviewed.

Ectopic pancreas is a congenital developmental anomaly that may be caused by embryologic errors. The pathogenetic details of ectopic pancreas remain unclear, but it has gradually been determined to originate at the gene level. DNA errors during embryological development cause ectopic pancreas. Ectopic pancreas is generally asymptomatic and harmless throughout the patient's entire life; in very rare cases, however, it can be symptomatic and harmful, causing pain, fever, bleeding, and other adverse effects. We herein report an unusual case involving a 52-year-old Japanese woman who presented with nausea and vomiting due to inflammation of an ectopic pancreas in the gastric antrum. Ectopic pancreatitis caused severe pyloric stenosis, and she was unable to ingest food or water even after admission to the internal medicine ward. Ectopic pancreatitis is a very rare clinical condition, but clinicians should be cautious of this uncommon disease in patients who develop gastric outlet obstruction without cancer or ulcers. The present case report is clinically significant because surgical treatment (distal partial gastrectomy) relieved the patient's serious distress rapidly and successfully after unsuccessful conservative treatments for acute ectopic pancreatitis. Antrectomy (distal partial gastrectomy) might be useful for ectopic pancreas, especially in case of gastric outlet obstruction due to the ectopic pancreatitis.
