Abstract
The occurrence of ectopic pancreas in the mediastinum is rare. Herein, we report a 22-year-old female who presented with right shoulder pain, dysphagia, fever and headaches. Chest computer tomography revealed a mass in the posterior mediastinum with accompanying signs of acute mediastinitis. Needle biopsy and fine-needle aspiration revealed ectopic gastral tissue and ectopic pancreas tissue, respectively. Surgical resection was attempted due to recurring acute pancreatitis episodes. However, due to chronic-inflammatory adhesions of the mass to the tracheal wall, en-bloc resection was not possible without major tracheal resection. Since then, recurring pancreatitis episodes have been treated conservatively with antibiotics. We report this case due to its differing clinical and radiological findings in comparison to previous case reports, none of which pertained a case of ectopic pancreas tissue in the posterior mediastinum with recurring acute pancreatitis and mediastinitis.

Abstract
Background Heterotopia of pancreatic tissue in the thorax and mediastinum is uncommon, although, a common developmental anomaly in the gastrointestinal tract where the aberrant tissue is a component of gastrointestinal duplication cysts, intralobular pulmonary sequestration or teratomas. Case presentation We report a case of an ectopic pancreas located in a giant mediastinal cyst in a 2-year old girl who presented with severe dyspnoea due to external compression of the intra-thoracic structures, mainly the right main bronchus. Surgical resection was carried out with complete relief of symptoms. The cyst was confirmed histopathologically to contain pancreatic tissue. Literature review showed that this is an uncommon presentation hence the need to report the case. Conclusion Heterotopia of the pancreas although, an uncommon occurrence in the thorax and mediastinum, should be considered when dealing with cystic lesions of the mediastinum and surgery plays an important role in its management.

Abstract
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.

Abstract
Mediastinal ectopic pancreas is a rare condition with only 28 cases reported in the literature. Here we report a 21-year-old female patient who presented with dyspnea and intermittent severe chest pain of 7 years' duration. Computerized tomography scan (CT-scan) of the chest revealed a mediastinal cyst. The cyst was resected and it demonstrated on histopathological examination the presence of pancreatic tissue with increased number of islets of Langerhans, coexistent with mediastinal cyst and thymic hyperplasia. We made a review of all previously reported cases of this entity.

Abstract
RATIONALE The incidence of heterotopic pancreas (HP) is relatively rare and mainly found in the upper gastrointestinal tract, and no case of HP cyst in the adrenal gland has been reported. Informed consent has been obtained from the patient for the publication of the case details. PATIENT CONCERNS A 21-year-old woman who presented with chronic lower back pain for a week without urinary disturbance or gastrointestinal discomfortable. DIAGNOSES Ultrasound (US) revealed a left renal cyst, and computed tomography (CT) showed a cyst in the area of the adrenal gland. INTERVENTIONS Cystectomy was successfully performed laparoscopically. Histopathologic examination of the removed cyst wall showed heterotopic pancreatic cyst accompanied by cystic degeneration. OUTCOMES No unusual drainage or abdominal signs were observed during the 6-month follow-up. LESSONS Despite of its rarity, HP accompanied by cyst formation in the adrenal gland area can present with waist pain. Therefore, the possibility of such disease needs to be considered. For thorough evaluation, in addition to abdominal US, CT, and/or magnetic resonance imaging, histopathological examination should sometimes be performed to make a definite diagnosis. Total excision and regular follow-up is necessary for such cases due to the potential risk of complications or recurrent cyst formation.

Abstract
Introduction: Ectopic pancreas is a rare developmental anomaly. It is a presence of pancreatic tissue without anatomic or vascular continuity with the normally developed pancreas. The most common heterotopic site is the stomach commonly involving antrum and prepyloric region on the greater curvature or posterior wall. Ectopic pancreas is diagnosed by endoscopic ultrasound, gastroscopy and biopsy, CT scan and MRI of the abdomen, a definitive diagnosis is verified by histopathological examination. Treatment is surgical. Case report: A 56-year-old woman presented with epigastric pain, nausea and fatigue. Esophagogastroduodenoscopy showed submucosal mass in the prepyloric region, biopsy was performed. Histopathological findings described normal gastric mucosa. Endoscopic ultrasonography and CT of the abdomen showed submucosal tumor, 18 mm in diameter, located in the prepyloric region. Surgical treatment was indicated. Gastrotomy with total extraction of tumor was performed. Histopathology findings showed ectopic pancreatic tissue in the submucosal and muscular layer of the stomach. Postoperatively patient fully recovered, and in the 2 year follow-up did not develop any symptoms related to gastrointestinal tract. Conclusion: Although presentation of ectopic pancreatic tissue in stomach is a very rare condition, it should be considered during gastroitestinal diagnostic in patients with nonspecific gastrointestinal symptomatology. In most of cases, for this patients, surgery is curative and definitive solution.

Abstract
BACKGROUND Heterotopic pancreas is a rare congenital condition characterised by pancreatic tissue lacking vascular or anatomic communication with the normal pancreas. Most cases of ectopic pancreas are asymptomatic. The preoperative diagnosis of this condition is difficult. CASE PRESENTATION A 50-year-old woman presented with dyspeptic symptoms of 4 years duration. Contrast enhanced CT (computed tomography) scan of abdomen suggested a gastrointestinal stromal tumour in the fundus of the stomach. The patient underwent laparoscopy assisted resection and subsequent histology revealed ectopic pancreatic tissue. CONCLUSION Although heterotopic pancreas is a rare lesion diagnosed on histology, it should be considered in the differential diagnosis of gastric mass lesions and in patients presenting with vague upper gastrointestinal symptoms.

Abstract
Ectopic pancreas is a well-known developmental anomaly found in approximately 2% of all autopsies, frequently in the gastrointestinal tract. Mediastinal pancreatic ectopia is very rare; only a few cases have been described in the English-language literature. According to previous reports, the pancreatic tissue is detected in the cyst wall or appears as small solid components of cystic masses within the anterior mediastinum. In this report, we present a case of ectopic pancreas appearing as a large solid mass in the anterior mediastinum of a 17-year-old male patient.

Abstract
Ectopia of the pancreatic tissue is a developmental anomaly found in ~2% of all autopsies, and 70~90% of these anomalies are located in the gastrointestinal tract. Mediastinal localization of an ectopic pancreas is extremely rare. Herein, we report two cases with mediastinal ectopic pancreas clarified by pathology and shown by thoracic contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI). In addition, a brief review of the relevant literatures is presented. Although CT and MRI manifestations of this lesion are nonspecific, certain notable findings need to be focused on. When there is a mass in the anterior mediastinum with marked and heterogeneous enhancement, along with necrotic and liquefied non-enhanced areas in the center, ectopic pancreas should be considered and differentiated from other neoplasms in this region.

Abstract
Background Heterotopic pancreas is defined as finding of pancreatic tissue without anatomic and vascular continuity with the normal pancreas. Heterotopic pancreas is a rare condition difficult to diagnose and with controversial clinical management. Case presentation We describe a 43 year old female patient previously submitted to laparoscopic gastric bypass for primary treatment of morbid obesity; 5 years later, the patient was discovered to have a mass in the antrum of the excluded stomach that was found to be heterotopic pancreatic tissue. Before gastric bypass surgery, the presence of the pancreatic mass in the gastric wall was unnoticed in the imagiologic records. Conclusion This is the first reported case of pancreatic heterotopy diagnosed in the excluded stomach after gastric bypass. A putative role of incretin hormones in mediating pancreatic cell hyperplasia of heterotopic pancreatic remnants should be considered an additional hypothesis that requires further research.

Abstract
UNLABELLED Ectopic pancreas in the mediastinum is extremely rare. We are reporting on a case of a twenty two year old woman who presented to our clinic with a large cervical mass. The CT scan revealed a cystic lesion in the anterior mediastinum. The patient underwent surgical resection by cervical approach. A Cystic mass with pseudocysts, cysts and complete pancreatic tissue were found in pathology. There were no signs of pancreatitis or malignancy. No recurrence was observed after a follow up of four years. We reviewed the case reports describing this rare condition in the medical literature.We conclude that the possibility of ectopic pancreatic tissue should be included in the differential diagnosis of anterior mediastinal cystic mass, though as a remote possibility. Surgery is probably needed for the diagnosis and treatment. Posterior mediastinal pseudocyst is a different entity associated with acute pancreatitis. In those cases surgery is not recommended. Our third conclusion is that pancreatic tissue should be actively sought, if a structure resembling a pseudocyst is found in an unexpected location.

Abstract
Ectopic pancreatic tissue is an uncommon developmental anomaly. The condition mostly occurs in the gastrointestinal tract and is usually asymptomatic. It rarely causes symptoms of inflammation, bleeding and perforation, and has potential for malignant change. Though it is an uncommon condition, cases of ectopic pancreas have been reported worldwide. Preoperative diagnosis of ectopic pancreas is challenging because of its nonspecific symptoms and signs. Owing to the revolution of minimally invasive surgery, submucosal tumors of the stomach can be resected by laparoscopic techniques. We have earlier reported on a case of ectopic pancreas in the stomach treated by robotics-assisted laparoscopic wedge resection. Herein, we report a case of ectopic pancreas in the prepyloric region of the stomach. A 44-year-old female presented with a two-week history of epigastralgia with radiation to the back. She received endoscopy check-up which disclosed a mass in the stomach. By endoscopic findings, a submucosal lesion in the prepyloric region with umbilical folding on the mucosa was identified. The umbilical folding on the mucosa hint the orifice of the duct of ectopic pancreas into the gastric mucosa suggestive of ectopic pancreas. Contrast-enhanced abdominal computed tomography showed a 5 cm cystic mass with heterogeneous content. To sum it up, the patient was diagnosed as ectopic pancreas in the stomach. She underwent laparoscopy-assisted antrectomy with Billroth I anastomosis (excision of the antrum and prepyloric region with reconstruction of gastrointestinal continuity by gastroduodenostomy) and had an uneventful hospitalization course. The histopathology of the resected tumor demonstrated ectopic pancreatic tissue in the gastric wall. To the best of our knowledge, excision of gastric ectopic pancreas using laparoscopy-assisted antrectomy with Billroth I anastomosis has never been reported in the literature.
