The advent of immune checkpoint inhibitors has revolutionized cancer treatment. These novel agents have provided promising treatment options in patients with different types of cancers. One of these agents is pembrolizumab, which works by blocking the binding of T-lymphocytes to programmed cell death ligand 1 receptors on tumor cells, thus enabling immune activation of T-lymphocytes against tumor cells. Pembrolizumab is commonly used in metastatic nonsmall cell lung cancer and melanoma. However, despite the remarkable efficacy this agent has achieved, multiple immune-related adverse events have been reported including hepatitis, colitis, thyroid dysfunction, and pneumonitis...
