Immune checkpoint inhibitors block the checkpoint molecules. Different types of cancer immune checkpoint inhibitors have been approved recently: CTLA-4 monoclonal antibodies (as ipilimumab); anti-PD-1 monoclonal antibodies (as pembrolizumab and nivolumab); and anti-PD-L1 monoclonal antibodies (as atezolizumab, avelumab, and durmalumab). We collect recent published results about autoimmune endocrine dysfunctions associated with cancer antibody immunotherapies.

Lymphocytic hypophysitis is an uncommon autoimmune disease. It may involve the adenohypophysis, neurohypophysis and pituitary stalk. It is most often encountered in pregnant women. Its diagnosis and management pose a significant challenge, as its clinical manifestation and appearance in imaging studies are difficult to distinguish from more common lesion of the sellar region (e.g., pituitary adenomas). We present the case of a 42-year-old man who presented with a chiasmatic syndrome, diabetes insipidus and hypopituitarism.
