A 1.5-year-old male Siberian Husky dog was presented with a history of progressive twitching and tetraplegia. The dog was humanely destroyed and at necropsy examination an incidental intramural white lesion measuring 10 × 15 × 5 mm was observed in the gallbladder. Histologically, the mass consisted of pancreatic tissue located in the tunica adventitia of the gallbladder. Immunohistochemistry revealed that the islets of Langerhans were positive for insulin, but negative for glucagon. In addition, the dog had non-suppurative meningoencephalitis associated with canine distemper virus infection. The gallbladder lesion was consistent with pancreatic choristoma and is the first case described in a canine gallbladder.

Gastric cancer is a significant health concern worldwide, and its diagnosis and management are of paramount importance. Ectopic pancreas (EP) refers to an embryological abnormality where healthy pancreatic tissue develops without anatomical, vascular, or neural communication with the normal pancreas. We report the case of a patient whose initial endoscopic evaluation suggested early gastric cancer, but computed tomography scan (CT scan) and endoscopic ultrasound (EUS) indicated a locally advanced tumor.

Background: Ectopic pancreas is a benign subepithelial tumor with an abnormal anatomical position, typically diagnosed incidentally as it does not produce symptoms and is challenging to identify in paraclinical studies. The incidence is very low, so our objective is to present the case of a patient with ectopic pancreas as a rare cause of obscure gastrointestinal bleeding.
Clinical Case: A 70-year-old man presented with melena, anemia, and weight loss.

Ectopic pancreas, also known as heterotopic pancreas, is a rare condition in which the pancreatic tissue is found outside its usual location in the gastrointestinal (GI) tract. It is commonly asymptomatic and benign, and is often discovered incidentally during routine imaging, endoscopy, surgery, or autopsy. However, complications can arise, such as inflammation, bleeding, obstruction, or even malignant transformation, necessitating surgical intervention in some cases.
