Heterotopic pancreas is a relatively infrequent lesion most often found in the stomach. Four histologic types are recognized: total, canalicular, exocrine, and endocrine heterotopia. To our knowledge, only 2 cases of purely endocrine heterotopic pancreas have been reported in detail Pancreatic heterotopia; review of the literature and report of 41 authenticated surgical cases, of which 25 were clinically significan Pancreatic tissue outside boundaries of pancreas without anatomic or vascular connections to pancreas Also called ectopic pancreas Present in 0.5 - 14% of autopsies Due to displacement of pancreatic tissue during embryonic developmen Heterotopic pancreas is a congenital anomaly in which pancreatic tissue is anatomically separate from the main gland and without vascular or ductal continuity. It is variably referred to as ectopic, aberrant, or accessory pancreas, as well as pancreatic choristoma and adenomyoma
Pancreatic heterotopia is a rare and often incidental finding in clinical practice. The term refers to pancreatic tissue distinct from the normal pancreas and with its own ductal and vascular supply. Usually asymptomatic, ectopic tissue is still prone to infection and may cause clinical complications when mistaken for malignancy or abscess Heterotopic pancreas is a congenital anomaly in which pancreatic tissue is anatomically separate from the main gland . This entity is rarely symptomatic and its malignant transformation is even rarer. However, when present, it poses a diagnostic dilemma to clinicians, as little help comes from gastroenteroscopy and imaging Heterotopic pancreas (HP) in the stomach can be difficult to diagnose and there are many treatment options. The aim of this article is to review the contemporary diagnosis of and treatment options for HP in the stomach
Pancreatic heterotopia (PH), a congenital anomaly of the exocrine pancreas, is defined as the existence of the pancreatic tissue in topographic anomaly, with no anatomic, neural, or vascular connection to the main pancreas. The exact etiology of ectopic pancreas remains unclear Pancreatic heterotopia was first characterized by Jean Schultz in 1729 and is defined as any pancreatic tissue found outside the location of the normal pancreas. It is believed to arise during embryologic formation of the pancreas and is most commonly found in the stomach, duodenum, and jejunum, with rare cases identified in the biliary tree. Pancreatic heterotopia can occur within any portion of the digestive tract. In 90% of patients, the heterotopia is found in the stomach (38 %), duodenum (36 %), or jejunum (16%) . Eighty-five percent to 95% of gastric heterotopic pancreas is located within 5-6 cm of the pylorus
Heterotopic pancreatic tissue is frequently found throughout the upper gastrointestinal tract with a propensity to be located within the stomach, duodenum and jejunum 3. Most cases are discovered incidentally, as heterotopic pancreatic tissue is typically asymptomatic 2 Pancreatic and gastric heterotopia are the two predominantly occurring heterotopic tissues in the GI tract. , The prevalence of ectopic pancreatic tissue in the GI tract ranges from 0.6% to 13.7% of autopsy series and it can be present anywhere in the GI tract with the most common localizations being stomach (27.5%), duodenum (25.5%. Pancreatic heterotopia is a rare anomaly characterized by aberrantly located pancreatic tissue not having continuity with the pancreas. The usual sites involved include the gastric antrum, duodenum, jejunum, Meckel's diverticulum, colon and ampulla of Vater while the rarest is the gallbladder
Pancreatic heterotopia is a rare congenital disorder occurring at a variety of sites in the gastrointestinal tract. It is rarely symptomatic. Despite advances in diagnostic techniques, it still remains a challenge to the clinician to differentiate it from a neoplasm A series of 212 cases of pancreatic heterotopia has been analyzed in order to ascertain the frequency of this congenital anomaly and to determine the cause of significant clinical symptoms. In the period from 1952 through 1971, 212 cases of heterotopic pancreas were seen at the Mayo Clinic. A firm..
Pancreatic heterotopia is a very rare entity, when it is located in the gallbladder wall. But with the potential to cause severe .

Pancreatic heterotopia most commonly occurs in the upper gastrointestinal tract, but can occur in other sites, including Meckel's diverticulum. When multiple histologic elements of the pancreatic tissue (acini, ducts, and endocrine cells) are present, the diagnosis is typically straightforward As previously stated, HP is one of the SM tumors and is defined as the presence of pancreatic tissue outside its normal location and without anatomic and vascular continuity with the main body of the pancreas . Usually asymptomatic, gastric heterotopia is commonly an incidental finding on imaging studies, at endoscopy or at autopsy [1, 4]
Autopsy studies suggest an incidence of 0.4-1% of all cases of pancreatic heterotopia. Heterotopic foci in the spleen are usually small and subcapsular. To the best of our knowledge, six cases of heterotopic pancreatic tissue in the spleen have been described in the literature, with cystic mucinous pancreatic neoplasms arising within all of. Pancreatic metaplasia in the gastric mucosa was first characterized by Doglioni et al. in 1993. Pancreatic acinar-like cells characterized was found in 101 cases (84 gastric biopsies and 17 gastrectomies) of 8,430 gastrectomies and gastric biopsies. These cells, arranged in nests or in variably sized lobules among the gastric glands Heterotopic pancreatic tissue could be histologically divided into the following four types: (A) those comprising all cell types (total heterotopia), (B) those composed of ducts only (canalicular heterotopia), (C) those comprising acinar cells only (exocrine heterotopia), and (D) those composed of islet cells only (endocrine heterotopia.

Pancreatic heterotopia or pancreatic ectopia is defined as pancreatic tissue found outside its normal location, without anatomic or vascular communication with the normal body of pancreas.1 The pathogenesis of pancreatic heterotopia is unknown. One hypothesis is that during embryonic development, small parts are separated from the pancreas.
Pancreatic heterotopia on the wall of the gallbladder is rare; Jean Schultz first described the condition in 1727, and Klob first confirmed its histopathology in 1859 [1, 6, 8]. The incidence of pancreatic heterotopia generally ranges from 0.55% to 13.7% in autopsy series and 0.2% in laparotomies [1, 4, 8, 9] Pancreatic heterotopia is defined as pancreatic tissue that is not normally situated, has no contact with the normal pancreas, and possesses its own duct system and vascular supply.5,6 It contains any mixture of tissues that may be found in the pancreas but usually consists primarily of ducts and surrounding simple mucin-producing glands.
Objective: The spectrum of pancreatic heterotopia will be reviewed, including clinical features, potential complications, and imaging manifestations. This will also include a review of various entities associated with pancreatic heterotopia such as groove pancreatitis and cystic dystrophy of gastroduodenal heterotopic pancreas Pancreatic heterotopia has been defined as the occurrence of pancreatic tissue in aberrant anatomic sites that lack vascular, neural and anatomic continuity with the pancreas. 1 In general, pancreatic heterotopia is rare and postmortem frequency rates range from 0.6% to 13.7%. 2 It is usually asymptomatic and the common gastrointestinal.
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.

Adenomyomas of the stomach are rare tumours characterised by duct/gland-like structures embedded within a smooth muscle stroma. Although the histogenesis of adenomyomas remains unclear, the histological appearance has justified the assumption that these are abortive forms of pancreatic heterotopia. We report an unusual case with simultaneous and independent appearance of both adenomyoma and. Pancreatic heterotopia may be found in all age groups, although the condition is only rarely en-countered in children. This is a little surprising in view of the fact that the condition is usually con-sidered to be an antenatal anomaly. It manifests it-selfmostfrequently in the fourth andfifth decades, and seems to be somewhat more common in.
Pancreatic heterotopia is a rare congenital anomaly resulting from failure of pancreatic cell migration, and is found as an incidentaloma in imaging or surgeries. Although it is a rare disease, nesidioblastosis should be considered in the investigation of hypoglycemia, even in the rare presentation of nesidioblastosis in patients with. Pancreatic heterotopia is defined as pancreatic tissue located outside the gland without any anatomical or vascular connection to the pancreas . Ectopic pancreatic tissue in gastrointestinal tract is found in 0,6-13,7% of autopsy series and the most common localizations are stomach (25-60%) and duodenum (25-35%)  True pancreatic heterotopia (i.e., pancreatic parenchyma without anatomic or vascular con- Cytology nections to the pancreas itself) must be distinguished from Tru-Cut biopsies and FNA of the submucosal mass were pancreatic acinar metaplasia.

Gastric and pancreatic heterotopia has been well documented at various sites in the gastrointestinal tract, with a reported incidence of 1- 13% . Pancreatic heterotopia is mostly seen in the stomach, whereas combined (gastric and pancreatic) heterotopia is most commonly seen in the duodenum and jejunum
Pancreatic heterotopia is a well-described entity occurring at multiple abdominal sites, most commonly the stomach and small intestine. They can develop similar disease processes as the pancreas ranging from acute pancreatitis, cyst formation, or neoplasms, most commonly ductal adenocarcinoma The 2021 edition of ICD-10-CM K86.8 became effective on October 1, 2020.

Pancreatic heterotopia is found in both the stomachandduodenum, while in Meckel's diverticulum gastric mucosaorpancreatic tissue can beseen.' of combining metaplasia and true heterotopia under the term heterotopic gastric mucosa. As a result many of the conclusions drawn seem to be incorrect Although the cause of pancreatic rest remains unclear, several theories, including the 'theory of metaplasia,' the 'theory of misplacement' and the latest addition, the 'theory of abnormalities of notch signaling', have been proposed to explain the pathogenesis and occurrence of pancreatic heterotopia tions, true duodenal wall or pancreatic head cysts, and pancreatic head heterotopia in the duodenum [2, 5, 7]. Groove pancreatitis is usually classified into pure and segmental forms . The pure form affects exclusively the groove. The seg-mental form extends to the pancreatic head despite a clear predominance in the groove [1, 2] (Fig. 1)
