Unlabelled: Intrahepatic heterotopic pancreas is rarely reported in the literature. Here, we report a case of a 39-year-old male with intrahepatic heterotopic pancreas associated with primary cholesterol hepatolithiasis. Computed tomography (CT) scans revealed multiple cholesterol stones in intrahepatic bile ducts of the left lobe concomitant with intrahepatic cholangiectases. These observations were confirmed by magnetic resonance cholangiopaneretography (MRCP). The patient underwent transabdominal left hepatic lobectomy. Postoperative histological examination of the resected specimen showed pancreatic tissues distributed along the wall of the bile duct and composed of acinar cells and duct elements without islets of Langerhans, therefore strongly suggesting that the heterotopic pancreas occurred in response to chronic injury due to the primary cholesterol hepatolithiasis and was derived from the biliary epithelial cells.

Heterotopic pancreas (HP) refers to the presence of ectopic pancreatic tissue located outside of the normal pancreatic location without anatomical or vascular continuity with the pancreas. HP within the gallbladder (HPGB) was first described by Otschkin in 1916. It remains an exceedingly rare pathology with few reported cases.

Background: Treatment with immunotherapy can elicit varying responses across cancer types, and the mechanistic underpinnings that contribute to response vrsus progression remain poorly understood. However, to date there are few preclinical models that accurately represent these disparate disease scenarios.
Methods: Using combinatorial radio-immunotherapy consisting of PD-1 blockade, IL2Rβγ biased signaling, and OX40 agonism we were able to generate preclinical tumor models with conflicting responses, where head and neck squamous cell carcinoma (HNSCC) models respond and pancreatic ductal adenocarcinoma (PDAC) progresses.

Background: Heterotopic pregnancy and amniotic embolism are rare conditions that can be challenging to diagnose. To date, there are no cases of heterotopic pregnancy associated with amniotic embolism described in the literature. Therefore, we report the case of a pancreatic heterotopic pregnancy, which led to amniotic embolism and an unfavorable maternal outcome.

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.
