CASE Herein we present a case accompanied by a defective perforin gene defect in the primary HLH pathogenesis, Covid-19 infection with the presence of fever and hyperferritinemia, which was evaluated in favor of reactivation and the patient was given both the HLH-2004 chemotherapy protocol treatment and COVID -19 therapy as recommended by the guidelines. Our patient improved clinically and in terms of laboratory test results at the end of the 15 th < /sup > day of hospitalization and was discharged.
