A sixty years-old patient was admitted with a gastric tumor corresponding to an adenocarcinoma developed in ectopic pancreatic tissue. Hundred cases of gastric heterotopic pancreas are shown in literature. This entity may remain asymptomatic. Symptoms such abdominal pain are described as the result of tumour growth. Carcinogenesis of ectopic pancreas (EPa) is however rare. Diagnosis is rarely pre-operative because modern imaging depicts a gastric tumour with no more information. The only treatment is surgery, with a best interest in frozen sections to direct the procedure, in this case a total gastrectomy with D2 lymphadenectomy. Based on this case report, an analysis of the literature focusing on diagnosis and treatment is presented.

Heterogeneity of pancreatic neoplasms arising in pancreatic heterotopia: a single institution review.

Article Synopsis
- Pancreatic heterotopia (PH) is when pancreatic tissue forms in the gastrointestinal tract and can have various health issues, though cancer development in PH is very uncommon.
- A study reviewed 163 PH cases from 1990 to 2020, finding that 7 had neoplastic processes, including different types of tumors.
- Most affected patients were men around 64 years old, with symptoms such as weight loss and abdominal pain, and it’s critical for pathologists to identify PH to ensure correct diagnosis and staging of potential tumors.
Heterotopic Gastric Mucosa in the Gallbladder: A Rare Case and Differential Diagnosis for a Gallbladder Polyp.

Heterotopia or ectopic tissue refers to the presence of normal tissue in an abnormal location, away from its typical anatomic site. While heterotopia is not uncommon, its occurrence in the gallbladder is quite rare, and even more unusual is the presence of gastric heterotopia within the gallbladder. This case report describes a 41-year-old female patient with oxyntic-type heterotopic gastric mucosa in the proximal body of the gallbladder.

Pancreatic heterotopia is the presence of pancreatic tissue in a different anatomical location with no connection to the main pancreas. The most common locations in the gastrointestinal system are duodenum, stomach, and Meckel diverticulum. However, it is quite rare in the hepatobiliary system.

The First Affiliated Hospital of Zhejiang Chinese Medical University (Zhejiang Provincial Hospital of Traditional Chinese Medicine), Hangzhou, Zhejiang, China.
Background: Heterotopic gastric mucosa in the upper esophagus (HGMUE) is considered to be accompanied by pharyngolaryngeal symptoms, whereas the association strength between HGMUE and pharyngolaryngeal symptoms remains controversial. This study assessed the strength of the association between HGMUE and pharyngolaryngeal symptoms using a meta-analytic approach.
Methods: PubMed, Embase, Web of Science, and CNKI databases were searched for relevant articles published between January 2010 and January 2024.
Article Synopsis
- A submucosal heterotopic gastric gland (SHGG) contains benign gastric tissue in the submucosa, and diagnosing related neoplasms through biopsy is difficult.
- A 74-year-old man had an upper stomach lesion found during endoscopy, leading to an endoscopic submucosal dissection (ESD) after a biopsy indicated a possible pyloric gland adenoma.
- The pathology confirmed SHGG with focal dysplasia, and the patient had a smooth recovery with no recurrence over 5 years, showcasing ESD's effectiveness in treating SHGG-related neoplasms.
