Secondary hemophagocytic lymphohistiocytosis (HLH) is most commonly associated with malignancy, infection, or an underlying autoimmune disorder. Malignancy-associated hemophagocytic syndrome is responsible for most secondary HLH cases, but it has not been well described in children. We present a case of a 4-year-old female with favorable histology of Wilms tumor who developed secondary HLH after unsuccessful resection of the tumor and initiation of chemotherapy.
