Fusarium rhinosinusitis post chimeric antigen receptor T-cell therapy.

Chimeric antigen receptor T-cell (CAR-T) therapy is a novel treatment for various types of hematologic malignancy. We presented a case of refractory diffuse large B cell lymphoma patient who developed acute invasive fungal rhinosinusitis (AIFR) from Fusarium species after CAR-T therapy. Our photos illustrated the classic clinical, endoscopic, and histopathologic findings of AIFR.
