The use of immune checkpoint inhibitors (ICIs) has drastically transformed the therapeutic landscape in lung cancer. Special focus has been put on immune-related toxicity; however, infections can also seem during ICI treatment. Although rare, tuberculosis (TB) has been increasingly identified after ICIs, and it seems that the programmed cell death protein 1 and programmed death-ligand 1 pathway is directly involved in its pathophysiology. Here, we describe the case of a patient with advanced NSCLC who developed abdominal TB after 32 months of pembrolizumab and who remains in tumor remission 10 months after discontinuation of this drug. Routine screening for latent TB before ICI treatment is advised, with closer collaboration between infectious disease specialists and oncologists.
