We herein report a case of fatal pancreatitis induced by an immune checkpoint inhibitor. A 62-year-old man with cancer of unknown primary was treated with pembrolizumab. After 12 cycles, immune-related pneumonitis developed and was treated with prednisolone. ⋯ Eight months later, another attack of pancreatitis occurred, which did not respond to therapy, including high-dose corticosteroids, and he eventually died. This is the first report describing fatal immune checkpoint inhibitor-related pancreatitis. Despite the rarity of this complication, attention should be paid to its potential severity and treatment.

Achilles tendon xanthoma (ATX) is one of the typical features of familial hypercholesterolemia (FH). The morphological evaluation of ATX by X-ray radiography is widely recognized; however, the utility of other imaging modalities remains unclear. ⋯ Neoangiogenesis accompanies chronic inflammation and it may play an important role in the deposition of cholesterol crystals leading to ATX. In addition to the morphological evaluation of ATX, the assessment of neoangiogenesis may therefore be essential for the evaluation of ATX.

Review Case Reports
Severe Acute Cholangitis and Bacteremia Due to Campylobacter jejuni: A Case Report and Review of the Literature.
Campylobacter jejuni is common cause of enteritis, but biliary infection rarely reported. An 82-year-old woman with pancreatic head cancer underwent endoscopic biliary drainage for malignant biliary obstruction. She was subsequently admitted for management of diarrhea. ⋯ She was diagnosed with acute cholangitis and bacteremia with C. jejuni. Endoscopic biliary drainage and antimicrobial administration improved her symptoms. As complications of C. jejuni diarrhea are rare, antibiotics are not necessarily indicated but sometimes are needed to prevent complications.
