Endometrial cancer is generally diagnosed at an early stage and has a good prognosis, although once it recurs, the prognosis is poor because of few therapeutic options. Since endometrial cancer has a high frequency of microsatellite instability‐high/mismatch repair deficiency, the anti‐PD‐1 antibody pembrolizumab is expected to be one of the key therapeutic agents for recurrent endometrial cancer. Immune‐related adverse events (irAEs) are autoimmune‐like unique and occasionally life‐threatening side effects of immune checkpoint inhibitors. Here, we report a rare case of recurrent endometrial cancer that showed long‐term complete remission after developing relapsing severe irAE colitis following the introduction of pembrolizumab.
