Graphical Abstract

The pathological investigations of the fatal fulminant inflammation in the diaphragm resulting from Pembrolizumab-related myopathy. Histologically, diaphragm demonstrated massive infiltration of inflammatory cells and muscle fiber necrosis.The mechanisms that explain the generation of PD-1 nyopathy are still unknown. We should therefore always pay close attention to the neuromuscular symptoms of patients treated with ICIs.
