摘要

Rationale:Autoimmune pancreatitis (AIP) is a special type of chronic pancreatitis, which is rarely associated with pseudocyst.Patient concerns:A 48-year-old man complained of a recurrent upper abdominal pain in our hospital.Diagnoses:A cystic mass of size 4x3cm in his pancreatic tail was found by computed tomography. The concentrations of serum carbohydrate antigen19-9 (81U/mL) and serum immunoglobulin G4 (181mg/dL) were elevated.Interventions:The patient received partial pancreatectomy with splenectomy and partial esophagectomy.Outcomes:Further histopathological examination revealed a pseudocyst, significant lymphoplasmatic infiltration, and fibrosis in the pancreas and esophagus. We report a rare case of AIP complicated with a pancreatic pseudocyst and invasion of lower esophagus.Lessons:Our study demonstrated that surgical therapy should be considered for the refractory AIP complicated with a pancreatic pseudocyst and invasion of lower esophagus.
