Immune checkpoint inhibitors (ICIs) such as nivolumab and ipilimumab are emerging agents for the treatment of cancers including melanoma. ICIs are known to cause immune-related adverse events (irAEs), including the development of enterocolitis, dermatitis, and nephritis. However, ICI-induced pancreatitis has seldom been reported, and its pathophysiology and clinical importance remain largely unknown. We describe a 76-year-old man with melanoma who developed acute pancreatitis without abdominal p...

Granulocyte colony-stimulating factor (G-CSF) is a relatively new drug that is used for recovery of chemotherapy-associated neutropenia. It is known to cause bone pain, headache and fatigue as side-effects; however, large-vessel vasculitis is extremely rare and its relation with G-CSF remains unknown. We describe a 49-year-old woman in whom arteritis developed after chemotherapy and subsequent G-CSF administration. She had experienced pinealoma 3 months ago and received surgery and chemotherapy,...

Abstract TAFRO syndrome is a rare variant of idiopathic multicentric Castleman's disease, for which disseminated non-tuberculous mycobacteria (NTM) infection must be excluded. However, due to the slow and fastidious growth of the organisms, identification of the pathogen is often challenging. We herein describe a case of disseminated Mycobacterium genavence infection, in which manifestations of the patient were confusingly similar to those of TAFRO syndrome. A 69-year-old Japanese man presented ...
