IntroductionThe introduction of immune checkpoint inhibitors (ICIs) has opened a new chapter in cancer treatment. Nevertheless, their use may result in immune-related adverse events (irAEs) with multifactorial determinants, complex mechanisms, and varying clinical implications. In specific cancer types, like melanoma, irAEs exhibit a complex relationship with patient outcomes.Case PresentationWe present a case of febrile neutropenia following ICI therapy in a patient with metastatic melanoma, underscoring the intricate clinical landscape associated with irAEs in the context of cancer immunotherapy. More specifically, a 68-year-old man was diagnosed with metastatic malignant melanoma and administered a combination of nivolumab and ipilimumab. However, after a single dose, the patient was hospitalized due to febrile neutropenia. The patient eventually recovered, but a diagnosis of myelosuppression related to prior immunotherapy led to treatment discontinuation. Subsequently, the patient transitioned to a second-line therapy.ConclusionThis case contributes to our comprehension of rare yet potentially severe hematological irAEs and their influence on immunotherapy outcomes. Such insights will guide future diagnostic and therapeutic strategies in the field of immunotherapy.
