A 78-year-old Japanese woman with no history of rheumatic disease received 2 doses of the BNT162b2 COVID-19 mRNA vaccine. Two weeks later, she noticed bilateral swelling in the submandibular region. ⋯ Treatment was started with prednisolone at 30 mg/day, and the organ enlargement improved. We herein report a case of IgG4-RD that may have been associated with an mRNA vaccine.

Bioprosthetic aortic valves have limited durability. We herein report sudden progression of structural valve deterioration (SVD) and a successful case of emergency transcatheter aortic valve (TAV) implantation for acute decompensated heart failure (ADHF) caused by SVD. ⋯ Emergency TAV implantation in the surgical bioprosthetic valve was selected based on the surgical risk. Ours and previous case reports suggest that SVD can progress suddenly, even after months of stability, and that emergency TAV implantation is effective.

Primary pancreatic lymphoma is a rare pancreatic malignancy, reportedly accounting for only 0.2-0.7% of all primary pancreatic tumors. Primary pancreatic lymphoma is often difficult to distinguish from other diseases, such as acute pancreatitis. We herein report the autopsy of a patient with primary pancreatic lymphoma with imaging findings resembling those of severe acute pancreatitis, with a focus on the gross and histological features.

Hiatal Hernia with Prolapse of the Pancreas Causing Bile Duct Stricture and Liver Function Disorders: A Case Report and Literature Review.
Hiatal hernia is a common condition in elderly patients, but the additional presence of prolapse of the pancreas is extremely rare. We herein report an 89-year-old woman who presented with liver function disorders and abdominal pain. ⋯ Our review of the literature identified three types of pancreatic herniations: asymptomatic, bile duct complication, and acute pancreatitis. Pancreatic head herniation tends to induce bile duct complications.
