“…There remains a question as to whether the pancreatic tissue in the accessory papilla region could be considered an ectopic pancreas. The ectopic pancreas is defined as pancreatic tissue that lacks continuity with the pancreatic parenchyma and differs in vascular supply [ 12 ]. It is commonly found in the gastrointestinal tract, such as the duodenum, stomach, and jejunum [ 13 ].…”

Case presentation A 61-year-old female was referred to our hospital with a neoplastic lesion in the duodenum. Computed tomography with contrast enhancement revealed a 10-mm tumor in the duodenum. Upper gastrointestinal endoscopy revealed a submucosal tumor-like lesion in the descending part of the duodenum. Endoscopic ultrasound revealed a well-defined hypoechoic tumor. Biopsy and immunohistochemical findings including negative Synaptophysin and Chromogranin A staining and positive Trypsin and BCL10 staining suggested a carcinoma with acinar cell differentiation. Pancreatoduodenectomy was performed, and the resected specimen had a 15-mm solid nodule in the submucosal layer of the duodenum. Pancreatogram of the resected specimen revealed a tumor localized in the accessory papilla region. In histopathological examination, the tumor was found in the submucosa of the duodenum with pancreatic tissue present nearby, and these were separated from the pancreatic parenchyma by the duodenal muscle layer. These findings led to a diagnosis of acinar cell carcinoma originating from the accessory papilla of the duodenum. Conclusion Acinar cell carcinoma originating from the accessory papilla of the duodenum is exceptionally rare, with no reported cases to date. The origin was considered to be pancreatic tissue located in the accessory papilla region.

“…The stomach, duodenum, and proximal jejunum are the parts of the upper gastrointestinal (UGI) tract where the EP most frequently develops. 2 The condition is typically asymptomatic, and most instances are discovered by accident. Rarely, it may occur suddenly with thoracic discomfort, vomiting, nausea, and abdominal pain.…”

Ectopic pancreas refers to pancreatic tissue that lacks vascular or anatomical connection with the main body of the pancreas. Superior mesenteric artery syndrome involves the compression of the third part of the duodenum between the aorta and the superior mesenteric artery. We present a case of a 12-year-old female with a 4-year history of recurrent episodes of severe epigastric pain, improved by sitting and leaning forward, and occurred monthly for nearly 48 h. Radiological findings confirmed the diagnosis of superior mesenteric artery syndrome. However, further investigation revealed the presence of ectopic pancreas. Surgical intervention successfully treated both conditions. The patient presented with severe abdominal pain, and although there was a diagnosis of superior mesenteric artery syndrome, the pain was not entirely attributable to this condition, as there was no correlation with food intake, and the degree of obstruction was mild. Further investigations revealed the presence of ectopic pancreas, which provided an explanation for the severity of the pain. This case highlights the need for further research on the potential association between superior mesenteric artery syndrome and ectopic pancreas.
