Abstract
Heterotopic pancreas is a relatively rare condition that may be associated to clinical complaints or signs. Here, we report a case of gastric heterotopic pancreas assictaed to ductal adenocarcinoma. Obstructive jaundice was the initial symptom prompting medical intervention. A 73-year-old male patient presented with yellow staining of the skin and sclera, and dull epigastric pain. Contrast-enhanced computed tomography showed stenosis of the extrahepatic distal bile duct and mass lesions of the antrum. The patient underwent tumor resection, distal gastrectomy (Billroth II), and common bile duct exploration. Postoperative pathological examination revealed an adenocarcinoma located in the wall of the gastric antrum. Immunohistochemical results suggested that the tumor originated from the pancreas. Heterologous pancreatic tissue and a dilated pancreatic duct were found in the tumor. These findings suggest malignant transformation of the gastric heterotopic pancreas. Of note, jaundice as clinical complaint for adenocarcinoma associated to gastric heterotopic pancreas.

Abstract
BACKGROUND Heterotopic pancreas is defined as pancreatic tissue located outside the pancreatic parenchyma that lacks an anatomic or vascular connection to the normal pancreas. Symptomatic gastric heterotopic pancreas is a rare condition that can manifest as acute or chronic pancreatitis. Asymptomatic heterotopic pancreas does not require treatment, while symptomatic lesions should be resected. The modality of final resection of heterotopic pancreas depends on its size and the depth of gastric wall involvement. METHODS AND RESULTS A 36-year-old woman was admitted for recurrent epigastralgia. Abdominal computed tomography (CT) scan revealed that an abscess had formed in the gastric antrum. After multidisciplinary discussion we decided for conservative treatment with intravenous antibiotics and further detailed endoscopic diagnostic. Esophagogastroduodenoscopy revealed a submucosal mass with a central fistula and intermittent pus secretion in the prepyloric region of the gastric antrum, which was subsequently drained with a double pigtail stent under endoscopic ultrasound (EUS) and fluoroscopy. The possibility of pancreatic fluid collection in the case of heterotopic pancreas was suggested during the EUS examination, and histology subsequently confirmed heterotopic pancreatic tissue. The patient was in good condition and without any abdominal pain. According to a control CT scan after 10 weeks, the fluid collection was completely resolved. Due to the possible recurrence of pancreatitis, resection of heterotopic pancreas was proposed to the patient. Since the lesion involved the muscularis propria of the gastric wall, surgical resection of the mass was indicated. CONCLUSION Fluid collections after acute pancreatitis in heterotopic pancreas in the gastric antrum can be successfully managed by endoscopy.

Abstract
ABSTRACT Malignant transformation of heterotopic pancreas is extremely rare. We describe FDG PET/CT findings in a case of pancreatic ductal adenocarcinoma arising from a heterotopic pancreas in the submucosa of the pylorus with peripyloric lymph node metastasis and elevated serum carbohydrate antigen 19-9 level. The heterotopic pancreatic adenocarcinoma showed intense FDG uptake, and the peripyloric lymph node metastasis showed mild FDG uptake. This case indicates that heterotopic pancreatic adenocarcinoma should be included in the differential diagnosis of FDG-avid gastric submucosal lesions, especially in patients with elevated serum carbohydrate antigen 19-9 level.

Abstract
RATIONALE Heterotopic pancreas is a pancreatic tissue that occurs outside the normal anatomical site, the most common site is antrum. Due to the lack of specific imaging and endoscopic signs, heterotopic pancreas especially those occurring in the rare site, are often misdiagnosed, and leading to unnecessary surgical treatment. Endoscopic incisional biopsy and endoscopic ultrasound-guided fine-needle aspiration are effective means for diagnosing heterotopic pancreas. We reports a case of extensive heterotopic pancreas in a rare site, which was finally diagnosed by this way. PATIENT CONCERNS A 62-year-old man was admitted due to the presence of an angular notch lesion, which was suspected as gastric cancer before. He denied any history of tumor or gastric disease. DIAGNOSES No abnormality was found in the physical examination and laboratory testing after admission. Computed tomography showed localized thickening of the gastric wall measuring 30 mm in the long diameter. Gastroscope revealed a nodular-like submucosal protuberance at the angular notch with size of about 3*4 cm. Ultrasonic gastroscope showed that the lesion was located in the submucosa. The lesion exhibited mixed echogenicity. The diagnosis can not be identified. INTERVENTIONS 2 times of incision biopsy were performed to make a clear diagnosis. Finally, appropriate tissue specimens were obtained for pathology testing. OUTCOMES The patient was diagnosed as heterotopic pancreas according to pathology. He was recommended to undergo observation and regular follow-ups rather than surgery. Then he was discharged home with no discomfort. LESSONS Heterotopic pancreas occurring in the angular notch is extremely rare, the site is scarcely reported in the relevant literature. Therefore, it is easy to be misdiagnosed. In the cases of an vague diagnosis, endoscopic incisional biopsy or endoscopic ultrasound-guided fine-needle aspiration may be a good choice.

Abstract
RATIONALE Aberrant pancreatic tissue in the gastrointestinal tract is a relatively common finding. However, malignant transformation is extremely rare. Herein, we report a case of ectopic pancreatic ductal adenocarcinoma in the stomach wall. PATIENT CONCERNS A 38 year old male presented with nausea, bloating, abdominal distention and weight loss for 4 months. DIAGNOSES Endoscopy of upper gastrointestinal tract was performed twice with 2 months interval and a stenotic pyloric part was observed with a suspected submucosal lesion. It was sampled both times, however the pathology findings of the mucosal biopsies were unremarkable with no identifiable neoplastic structures. CT scan and MRI was performed and showed a thickened pyloric wall with a submucosal lesion 15 × 15 mm in diameter. Blood levels of tumor markers carcinoembrionic antigen and carbohydrate antigen 19-9 were within a normal range. INTERVENTIONS Pyloric stenosis progressed and the patient underwent a Billroth type I distal gastric resection with D2 lymphadenectomy. Pathologic examination revealed a well differentiated ductal adenocarcinoma arising in the heterotopic pancreatic tissue (Heinrich type III). The resection margins and lymph nodes were free of tumor. The patient received adjuvant chemotherapy with 6 courses of XELOX. OUTCOMES No disease recurrence is reported in 12 months follow-up. LESSONS Aberrant pancreatic ductal adenocarcinoma in the stomach is a rare finding, however this pathology should be included in the differential diagnosis of gastric submucosal lesion causing pyloric stenosis.

Abstract
A 56-year-old woman was referred to our hospital due to dry mouth. Diagnostic upper gastrointestinal endoscopy showed slightly elevated lesions both on the anterior wall and lesser curvature in the upper part of the stomach. Biopsy-proven tuble-forming atypical cells in the two lesions led us to treat the presumed early gastric cancers with endoscopic submucosal dissection (ESD). Pathological examination of the ESD specimen showed well-differentiated malignant cells spreading widely in the submucosa with positive lateral and deep margins. On retrospective image re-evaluation after ESD, we noticed the correlation between the presumed early gastric cancers and the multiple submucosal cyst-like lesions in the gastric wall on computed tomography. Under the tentative diagnosis of gastric cancers originating not from orthotopic gastric mucosa but from submucosal ectopic gastric gland, the patient underwent laparoscopic total gastrectomy and regional lymph node dissection, revealing the tumor infiltration to the serosa and regional lymph node swelling. Postoperative pathological evaluation showed lymph node metastases, multiple submucosal cyst-like lesions lined with a single layer of presumably benign epithelium, papillary adenocarcinoma cells in the submucosa, and tubular adenocarcinoma cells both in the mucosal and subserosal regions. The patient was discharged on the postoperative 7th day without any events and completed adjuvant chemotherapy on an outpatient basis. General surgeons should note that cyst-like lesion(s) in the gastric wall might be a predictor of extensive submucosal cancer cell spreading even in a case of well-differentiated gastric adenocarcinoma.

Abstract
ABSTRACT A 77-year-old man was referred for a PET/CT 18F-FDG after incidental discovery of a lobulated jejunal lesion during surgery for an abdominal aortic aneurysm. The lesion was not removed due to the risk of digestive perforation. PET/CT 18F-FDG did not show pathologic hypermetabolism. Subsequently, we decided to perform PET/CT 18F-DOPA to better characterize this incidentaloma. A moderate uptake was showed, less than the pancreas. After multidisciplinary discussion, taking into account macroscopic and imaging aspects, the hypothesis of an ectopic pancreas was retained, allowing the exclusion of surgical excision.

Abstract
Background: Malignant transformation of heterotopic pancreatic tissue is a rare entity with only several case reports published in the scientific literature. Adjuvant chemotherapy following oncological resection for lesions with nodal metastasis has not been well described and there are no guidelines available to guide the management of these patients. Case Presentation: We present a case of gastric heterotopic pancreatic carcinoma with nodal metastasis in a young patient with breast cancer gene (BRCA) 2 mutation. He had undergone a laparoscopic wedge resection for a gastric lesion initially thought to be a gastrointestinal stroma tumor. Given the involvement of the wedge resection margins, the patient underwent a distal gastrectomy with oncological lymph nodal clearance. One out of the 33 harvested lymph nodes harboured micrometastasis while the main gastrectomy specimen did not have any residual malignancy. Following the histological diagnosis, he received an adjuvant chemotherapy regime akin to that prescribed for locally advanced pancreatic adenocarcinoma with good response. This is, to our knowledge, also the first such case report in a patient with BRCA2 mutation. Conclusions: Pre-operative diagnostic confirmation is challenging and endoscopic procedures pose significant false negatives. Reports of nodal metastasis following oncological resection are limited and there are no guidelines regarding adjuvant therapies. We would recommend a chemotherapy regimen similar to that for primary locally advanced pancreatic carcinoma in patients found to have nodal metastasis.

Abstract
BACKGROUND Ectopic pancreas in the ileum, including lesions within Meckel diverticulum, can cause severe manifestations and complications; yet, it was seldom reported in English literature. AIM This study aimed to raise awareness and provide information for better clinical management of this rare yet serious condition. METHODS A total of 1713 cases of small bowel resection were performed in our hospital between 2009 and 2018, among which 10 cases of ileac ectopic pancreas were identified. A comprehensive retrospective review of the 10 cases was taken. RESULTS Five lesions were located in the ileum wall and 5 were within Meckel diverticulum. Two lesions within Meckel diverticulum were incidental; the remaining 8 lesions were all associated with abdominal pain, gastrointestinal bleeding, and anemia. Of the 5 patients with lesions in the ileum wall, computed tomography uniformly revealed ileoileal intussusceptions with masses as lead points. Capsule endoscopies were performed in 6 cases, of which 3 showed positive findings. Double-balloon enteroscopy was conducted in one case and revealed an ileal diverticulum. Therapeutically, the offending bowel segments were removed, and intussusceptions were restored except for one case in which diverticulectomy was applied. No relapse or sequela was observed in the follow-up. CONCLUSIONS Ileac ectopic pancreas can be seen in the ileum wall or Meckel diverticulum. The majority of the lesions found in clinical practice present with abdominal pain, gastrointestinal bleeding, and anemia. Lesions in the ileum wall often cause ileoileal intussusception. Computed tomography, capsule endoscopy, and double-balloon enteroscopy are helpful preoperative examinations. Segmental small bowel resection is the treatment of choice.

Abstract
Although the presence of pancreatic tissue outside of the usual anatomical location of the pancreas is not an uncommon incidental finding, the risk of malignancy is extremely low. We report a case of ductal adenocarcinoma arising within a focus of heterotopic pancreas, occurring in the jejunum of an 81 year old woman. The patient presented with a history of progressive gastrointestinal occlusive symptoms. Computerized tomography showed a mass in the jejunum, which was surgically removed. Histopathology revealed an invasive pancreatic ductal adenocarcinoma from pancreatic tissue with no connection with the original gland (Heinrich type II). At the 12-month follow-up, there were no signs of recurrence. Despite the low risk of malignancy in heterotopic pancreas, adenocarcinoma is the most frequent histological type, and the prognosis is still not clear. Lesions incidentally detected during surgery and in symptomatic patients need to be removed by conservative procedures in order to exclude malignant disease.

Abstract
Malignant transformation of ectopic pancreas tissue is a diagnostic challenge as clinical symptoms and radiographic features of these tumors are non-specific. Given the rarity of these lesions, it is usually neither suspected nor included in the diagnostic workup of different tumors. We conducted a comprehensive literature review regarding malignancy arising from ectopic pancreas for a better understanding of its frequency, clinicopathological features, and prognosis. A literature search was performed in three major databases: PubMed, Cochrane, and Web of Science. Fifty-four well-documented cases of malignant ectopic pancreas were identified in the published literature. Our analysis provided the following observations: (1) there was a slight predominance of males over females; (2) most patients with malignant transformation of ectopic pancreas were middle-aged; (3) most commonly, the tumor was located in the stomach; (4) most tumors were adenocarcinomas; (5) most frequently, the malignancy arose within a type I heterotopia according to Heinrich classification; (6) macroscopically, a subepithelial-like appearance was most frequently observed; and (7) improved prognosis for ectopic pancreatic malignancies in comparison with reported survival data for orthotopic pancreatic cancer. Even if the majority of cases of ectopic pancreas are incidental findings and malignant transformation is a rare event, pancreatic heterotopy should be considered as a source of potentially malignant lesions.

Abstract
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.

Abstract
Resistant starch is as common soluble fiber that escapes digestion in the small intestine and can regulate intestinal function, metabolism of blood glucose and lipids, and may prevent tumorigenesis of gastrointestinal cancer. Epidemiology and other evidence have suggested that resistant starch may prevent colon cancer development. The aim of the current study was to explore the ameliorative effects and potential mechanisms of resistant starch in the tumorigenesis of colon tumors induced by dimethylhydrazine in C57BL/6 mice. Western blot analysis, ELISA, microscopy, immunofluorescence and immunohistochemistry were used to analyze the efficacy of resistant starch on the metabolic balance in the colon and tumorigenesis of colon tumors. The results demonstrated that a diet containing resistant starch decreased the animal body weight and reduced free ammonia, pH and short chain fatty acids in feces compared with mice that received a standard diet. Resistant starch reduced the incidence of colon tumors and suppressed the expression of carcinogenesis-associated proteins, including heat shock protein 25, protein kinase C-d and gastrointestinal glutathione peroxidase in colon epithelial cells compared with standard starch and control groups. Colon tumor cells proliferation and dedifferentiation were significantly decreased by a resistant starch diet. The results also demonstrated that resistant starch increased the apoptosis of colon tumor cells through regulation of apoptosis-associated gene expression levels in colon tumor cells. Oxidative stress and endoplasmic reticulum stress were upregulated, and elevation eukaryotic translation initiation factor 2α (eIF2α), activating transcription factor-4 and secretase-β expression levels were increased in the resistant starch diet group. Additionally, the activity of eIF2α and PERK were increased in colon tumor cells from mice that had received resistant starch. Increasing DNA damage-inducible transcript 3 protein (CHOP), binding immunoglobulin protein (BIP) and caspase-12 expression levels upregulated by resistant starch diet may contribute to the resistant starch-induced apoptosis of colon tumor cells induced by 1,2-dimethylhydrazine. In vitro assays demonstrated that knockdown of eIF2α inhibited apoptosis of colon tumor cells isolated from mice fed with resistant starch, which also downregulated CHOP, BIP and caspase-3 expression levels compared with controls. Furthermore, long-term survival of experimental mice was prolonged by the resistant starch diet compared with the standard diet group. In conclusion, the results indicate that resistant starch in the diet may prevent carcinogenesis of colon epithelial cells, mediated by enhancing apoptosis through an endoplasmic reticulum stress-mediated mitochondrial apoptosis pathway.

Abstract
Heterotopic pancreas (HP) can be detected by accompanying symptoms or incidentally during gastrointestinal (GI) tract tumor resection. We compared clinicopathologic features among 165 resected HPs (57 gastric [35%], 56 duodenal [34%], 30 omental [18%], and 22 jejunal [13%]). Symptomatic HPs (79/135 GI tract wall HPs, 59%) were larger (P=0.05), more common in younger patients and in a gastric location (both P<0.001), and more frequently associated with lymphoid cuffs (P=0.03) than incidentally found HPs. Gastric/jejunal HPs were more frequently symptomatic (P<0.001), deeply located (P=0.03), and associated with lymphoid cuffs (P=0.008) and pancreatic intraepithelial neoplasia/intraductal papillary mucinous neoplasms (PanIN/IPMN; P=0.001) than duodenal HPs. HP was frequently associated with acinar-ductal metaplasias (117/135 GI tract wall HPs, 87%) and PanINs/IPMNs (68/135, 50%); those with PanINs/IPMNs were larger (P<0.001), more frequently located in stomach (P=0.001), had deeper wall involvement (P=0.03), and more often showed infiltrative growth (P<0.001) and lymphoid cuffs (P=0.02). Four HPs containing PanINs abutted adenocarcinomas, all expressing wild-type KRAS and intact SMAD4/DPC4 expression. Thus, symptomatic HP is associated with younger age, larger size, gastric location, and lymphoid cuffs. HPs containing PanINs/IPMNs (usually low grade) are larger and more common in stomach, have deeper wall location, and show infiltrative growth and lymphoid cuffs. Adenocarcinomas are rarely observed adjacent to HPs with PanINs/IPMNs. KRAS mutational and SMAD4/DPC4 immunohistochemical studies can discriminate between adenocarcinoma derived from HP and concurrent adenocarcinoma with HP.

Primary pancreatic-type acinar cell carcinoma of the jejunum with tumor thrombus extending into the mesenteric venous system: a case report and literature review. BMC Surg 2017; 17:75. [PMID: 28662660 PMCID: PMC5492367 DOI: 10.1186/s12893-017-0273-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2017] [Accepted: 06/26/2017] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Although ectopic pancreatic tissue is common in the upper gastrointestinal tract, the incidence of ectopic pancreatic tissue in the jejunum is low, and malignant transformation in ectopic pancreatic tissue is rare. Furthermore, pancreatic-type acinar cell carcinoma (ACC) developing in the jejunum and ACC accompanied by tumor thrombus are extremely rare. CASE PRESENTATION A 78-year-old-woman presented with melena. Abdominal computed tomography images and endoscopic examination revealed a submucosal jejunal mass with tumor thrombus extending into a jejunal vein. The patient underwent a curative resection combined with a partial jejunectomy and partial pancreatectomy. Histopathological examination of the resected tissue showed tumor cells with a homogeneous acinar architecture identical to pancreatic-type ACC and tumor thrombus. Postoperatively, she was followed for 10 months and had no recurrence. CONCLUSION We present an extremely rare case of pancreatic-type ACC in the jejunum with extensive tumor thrombus invading into the mesenteric venous system. This type of cancer has not been reported previously but should be considered in the differential diagnosis of a jejunal mass.
