Background. < 7b > Hemophagocytic lymphohistiocytosis (HLH) may precede malignancy, in particular lymphomas and leukemias. However, the causative factors, appropriate treatment and the prognosis of this association is not established.

Case. Herein, we present two patients, one with nodular sclerosing Hodgkin lymphoma (HL) and concomitant Epstein-Barr virus (EBV) infection, and the other with anaplastic large cell lymphoma (ALCL), presented as malignancy associated HLH.

Conclusion. In our patients, malignancy directed therapy was sufficient to treat HLH symptoms both at presentation and at recurrence in the second patient.
