Purpose: This case report is to present the anatomical variation of ectopic pancreas and discuss about its clinical significance.

Methods: While dissecting an adult cadaver specimen, an ectopic pancreas specimen was found.

Results: The ectopic pancreatic tissue was located in the left lobe of the liver and the mesentery. After HE staining and microscopic observation, it was found that the ectopic pancreatic tissue contained ducts, islets, and acini, thus it was classified as Type I according to Gaspar Fuentes' classification.

Conclusion: We report an atypical variation of ectopic pancreas, which is located in the left lobe of the liver and the mesentery. This may be associated with certain digestive system diseases such as dyspepsia. The findings of this study can provide insights for the clinical diagnosis of digestive system diseases.

This study aimed to quantitatively analyze the characteristics of abdominal ectopic fat deposition in patients with different glucose tolerance by using mDixon Quant MRI. A total of 98 patients and 38 healthy volunteers were included in this study. The patients were stratified as impaired glucose tolerance (IGT) group (n = 18), the duration of diabetes less than 5 years (DMa group, n = 31) and longer than 5 years(DMb group, n = 49).

Pancreatic steatosis is defined as the ectopic accumulation of fat in the pancreas. While historically considered a benign incidental imaging finding, it is now recognized as a significant, and potentially reversible risk factor for pancreatic ductal adenocarcinoma (PDAC) independently of obesity. Although its epidemiology is not well characterized, meta-analysis data suggest an approximately 30% prevalence, with individual studies reporting even higher rates among patients with obesity and/or metabolic syndrome.

Ectopic pancreatic tissue (EPT) is a rare clinical condition characterized by the presence of pancreatic tissue without any anatomical or vascular connection to the main pancreas. We aim to present a highly unusual case of EPT (fewer than 40 reported cases in the literature), located in the wall of the gallbladder. A 41-year-old female presented with episodes of right upper quadrant and epigastric pain, nausea, and vomiting.
