The recommended treatment for a focal mass in the head of the pancreas is pancreaticoduodenectomy. Preoperative biopsy is not advised in patients who are candidates for resection because of the documented risk of tumour dissemination along the needle tract and significant false negative results.1 Autoimmune pancreatitis is a relatively uncommon condition that can present as a pancreatic mass and mimic malignancy. It may respond to glucocorticoid therapy, and further assessment of such treatment is indicated.2 Such experience will only accumulate if wider knowledge of this condition leads to clinical suspicion.

EUS-guided fine-needle biopsy fine-needle aspiration for histopathological evidence for type 1 autoimmune pancreatitis: A single-center retrospective study in China.

Background And Objectives: EUS is recommended for guiding pancreatic tissue acquisition in suspected autoimmune pancreatitis (AIP) cases. However, there is a lack of comparative research on the effectiveness between EUS-guided fine-needle aspiration (EUS-FNA) and EUS-guided fine-needle biopsy (EUS-FNB) for diagnosing AIP in China. This study aimed to evaluate the diagnostic accuracy of EUS-guided tissue acquisition (EUS-TA) specifically for type 1 AIP.

IgG4-related disease (IgG4-RD) is an autoimmune disease of unknown cause. is a transcription factor involved in immune responses, and its dysfunction leads to uncontrolled immune responses. We performed, to our knowledge, the first methylation analysis in type 1 autoimmune pancreatitis (denoted simply as AIP), a representative IgG4-RD.

Immunoglobulin G4-related disease (IgG4-RD) and systemic lupus erythematosus (SLE) are multisystemic autoimmune disorders that can present with renal manifestations. Overlapping cases of these diseases are extremely rare and present both diagnostic and therapeutic challenges. We report the case of a 70-year-old male with a history of autoimmune pancreatitis, who was admitted with fatigue, weight loss, and worsening kidney function.

Background: Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), can affect the hepatobiliary system and pancreas, substantially impacting the life quality of patients.
Objectives: To evaluate the quality of evidence and comprehensively assess the validity of associations of IBD with hepatobiliary and pancreatic diseases.
Design: We performed an umbrella review of existing meta-analyses in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) recommendations.
Background: Autoimmune pancreatitis (AIP) is a form of chronic pancreatitis that presents clinically with obstructive icterus, histologically with infiltration of pancreatic parenchyma by inflammatory cells leading to chronic inflammation with fibrosis, and therapeutically with good response to corticosteroid therapy. Clinically, it may resemble malignant disease, making diagnosis difficult and requiring a multidisciplinary team (gastroenterologist, endoscopist, radiologist, surgeon, pathologist). Two types of AIP are distinguished.
