Multiple drugs: Various toxicities and lack of efficacy.

A 26-year-old man with recurrent classical Hodgkin lymphoma (cHL) developed cytokine release syndrome (CRS), haemophagocytic lymphohistiocytosis (HLH)-like syndrome, and diabetic ketoacidosis while being treated with brentuximab-vedotin and nivolumab.
