Case in brief
A male in his early 70s with advanced EBV-positive mixed-cellularity classic Hodgkin lymphoma presented with cervical lymphadenopathy, fever, and hepatosplenomegaly. Despite initial chemotherapy, he developed hemophagocytic lymphohistiocytosis (HLH) characterized by persistent fever and cytopenia. Administration of rituximab led to rapid resolution of fever and significant improvement in laboratory markers, allowing continuation of chemotherapy, which resulted in a complete response.
Diagnostic / clinical pearl
Rituximab may be an effective adjunctive treatment for refractory HLH associated with EBV-positive classic Hodgkin lymphoma, particularly when standard therapies are insufficient.
