A high-quality pancreatic protocol computed tomography (CT) is the primary imaging modality for diagnosing and staging pancreatic malignancy. The main limitation of CT is the lack of sensitivity for early pancreatic lesions. Endoscopic ultrasound (EUS) provides an excellent complement to CT for both diagnosis and staging of pancreatic cancer, and allows easy access for needle aspiration and tissue diagnosis. Magnetic resonance (MR) can be helpful for evaluating small hepatic nodules or cystic lesions of the pancreas, but in general, the role of MR and positron emission tomography remains limited to special situations when the results of CT and EUS are equivocal.

Pancreatic cancer, often diagnosed at advanced stages, has poor survival rates. Effective screening aims to detect the disease early, improving outcomes. Current guidelines recommend screening high-risk groups, including those with a family history or genetic predispositions, using methods like endoscopic ultrasound and MRI.

Liver metastases from melanomas, sarcomas, and renal tumors are less frequent. Treatment and prognosis will depend on whether they are isolated or multiple, size and location, the presence or absence of extrahepatic neoplastic disease, age, stage of the initial disease, initial treatments instituted, time of evolution, and clinical condition of the patient. Recently, a high number of oncological therapies including monotherapy or in combination, neoadjuvants or adjuvants, and immuno-oncological treatments have been developed and tested, increasing disease-free time and survival.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) is associated with poor prognosis. The roles of the transcription factor special AT-rich binding protein-2 (SATB2) and β-catenin in PDAC have been a subject of controversy. We aimed to assess the diagnostic and prognostic impact of SATB2 and β-catenin in PDAC.

Context: Type 1 diabetes (T1D) is characterized by the presence of autoantibodies on a genetic background largely determined by HLA class II haplotypes. Stage 1 T1D is characterized by the presence of multiple autoantibodies and normoglycemia.
Objective: To investigate the prevalence of high-risk HLA-DQB1 haplotypes and the extent of islet autoimmunity in pancreatic tissues from non-diabetic organ donors with autoantibodies.

Background: T/histiocyte-rich large B-cell lymphoma (T/HRBCL) is a highly aggressive subtype of diffuse large B-cell lymphoma characterized histologically by the presence of a few neoplastic large B cells amidst an abundant background of reactive T lymphocytes and/or histiocytes. T/HRBCL commonly affects the lymph nodes, followed by extranodal sites, such as the spleen, liver, and bone marrow, with rare occurrences in the gastrointestinal tract. Primary gastrointestinal T/HRBCL lacks specific clinical and endoscopic manifestations, and it is difficult to differentiate from inflammatory diseases, nodular lymphocyte predominant Hodgkin lymphoma, and other diseases on a histological basis, thereby hindering early diagnosis.
