Pembrolizumab, a PD-1 checkpoint inhibitor, is widely used in the treatment of various malignancies. While it improves overall survival, it can lead to immune-related adverse events (irAEs), including rare endocrine disorders such as primary adrenal insufficiency (PAI). We present a case of PAI induced by Pembrolizumab in a 75-year-old man, emphasizing the importance of early recognition and timely management.
