Immune Checkpoint Inhibitors (ICI) are valuable therapeutic agents that enable targeted oncological treatment by interfering with key evasion mechanisms used by cancer cells. However, this therapy, by inducing a T-cell-mediated immune response disinhibition, can potentially trigger a cascade of immune toxicity with a wide range of manifestations affecting multiple systems. Myasthenia Gravis (MG) as an adverse effect of immune checkpoint inhibitors has a reported incidence of approximately 0.24%. Despite its low incidence, when it occurs as an immune-mediated adverse effect, it carries a high mortality rate, emphasizing the importance of the early recognition of its manifestations. We present a case of a 68-year-old male who developed de novo myasthenic syndrome as a secondary adverse effect of anti-PD-L1 therapy, specifically Atezolizumab.
