Blue hair pigmentation as inmunorelated adverse event in patient with non-small cell lung cancer (NSCLC) treated with anti- PD1 immunotherapy: a case report

Abstract

Currently there are new treatments available for the treatment of cancer. Consequently, there are new adverse reactions that should be known.Step by step, with the experience of using these new therapies, rare side effects are reported. In the case of immunotherapy, the appearance of immuno -related adverse effects may be associated with a longer survival and/or with a sustained tumor response over time. We report the case of a 69 year old male diagnosed with NSCLC, being treated with antiPD1 presented blue hair pigmentation as a side effect of treatment. It is a rare phenomenon, not previously described, that in our patient was associated with a longer survival despite the discontinuation of treatment.
