Case Reports
Erdheim-Chester Disease with Pancreatic Enlargement Observed Using Contrast-enhanced Endoscopic Ultrasonography.
We herein report an unusual case of Erdheim-Chester disease (ECD), a rare non-Langerhans cell histiocytosis, and emphasize its unique presentation and diagnostic challenges. Our patient exhibited uncommon symptoms and significant organ involvement, particularly pancreatic enlargement that is not typically associated with ECD. ⋯ This is the first report to document pancreatic lesions in patients with ECD evaluated using CEH-EUS. EUS-FNA is valuable for diagnosing rare diseases, including ECD, with diffuse pancreatic enlargement.

Review Case Reports
Simultaneous Occurrence of Hyponatremia and Hypokalemia in a Patient with Herpes Zoster: A Case Report with a Review of the Literature.
We herein report a patient with herpes zoster (HZ), severe hyponatremia, and hypokalemia. Syndrome of inappropriate antidiuresis (SIAD) leads to euvolemic hyponatremia and hypoosmotic plasma due to inadequate diuresis. ⋯ Hypokalemia is caused by hypercortisolemia, which is stimulated by HZ pain. Adequate treatment for HZ and comprehensive pain control play pivotal roles in improving SIAD, cortisol hypersecretion, and the subsequent electrolyte abnormalities.

Review Case Reports
Late-onset Rupture of the Intrahepatic Pseudoaneurysm Developed by Endoscopic Ultrasonography-guided Hepaticogastrostomy: A Case Report and Literature Review.
Endoscopic ultrasonography-guided hepaticogastrostomy (EUS-HGS) has emerged as an alternative drainage technique for patients with malignant biliary obstruction. However, few reports have discussed the occurrence of late-onset rupture of hepatic artery pseudoaneurysms following EUS-HGS. A recently available drill dilator equipped with a long screw segment was used in the dilation step of EUS-HGS. We highlight the potential concern that this long screw segment may increase the risk of damage to the hepatic artery, leading to late-onset life-threatening rupture of a pseudoaneurysm.

We herein present the case of a 21-year-old male Japanese diabetic patient with Temple syndrome, caused by maternal uniparental disomy of chromosome 14. The patient was overweight and had type 2 diabetes, dyslipidemia, metabolic dysfunction-associated steatotic liver disease, and microalbuminuria. ⋯ This may lead to insulin resistance due to the absence of delta-like homolog 1 (DLK1) and retrotransposon gag-like 1 (RTL1). The patient had experienced social withdrawal at home (hikikomori in Japanese), had poorly controlled type 2 diabetes, and was overweight despite receiving diet therapy and oral hypoglycemic agents.

A 74-year-old woman developed acute severe colitis after receiving her sixth mRNA vaccine against coronavirus disease 2019 (COVID-19). On the day after vaccination, she experienced bloody diarrhea, abdominal pain, and high-grade fever. Laboratory tests revealed leukocytosis and increased C-reactive protein. ⋯ Her symptoms and laboratory findings improved immediately after the initiation of prednisolone therapy. Pre-discharge total colonoscopy revealed mucosal repair in most of the colon. Clinicians should acknowledge that severe acute colitis can occur after COVID-19 vaccination.
