Abstract

Hemophagocytic lymphohistiocytosis (HLH) has been reported as a rare complication of immune checkpoint inhibitors (ICI); however, ICI-related HLH is a life-threatening and comparatively late adverse event. Early diagnosis is critical, and it should be included in the differential diagnosis especially in patients with cytopenia with fever and hyperferritinaemia.

Keywords: haemophagocytic lymphohistiocytosis; immune checkpoint inhibitors; lung cancer.
