Proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitor use in the management of resistant hypercholesterolemia induced by mitotane treatment for adrenocortical cancer

We report the case of a patient with probable heterozygous familial hypercholesterolemia and mitotane-induced resistant hypercholesterolemia, despite combination therapy with rosuvastatin and ezetimibe. The patient was managed with the addition of evolocumab. Use of a proprotein convertase subtilisin-kexin type 9 inhibitor, should be considered in patients who develop mitotane-related hypercholesterolemia that cannot be managed with conventional lipid-lowering treatment.
