Invasive candidiasis is associated with high morbidity and mortality, and the rising of antifungal resistance underscores the need for new therapies. Rezafungin, a second-generation echinocandin, enables once-weekly dosing, achieves high plasma concentrations, and shows potent in vitro activity. We report two Brazilian cases showing its clinical utility: (i) fluconazole-resistant Candida tropicalis bloodstream infection in a patient with colorectal cancer and chronic kidney disease and (ii) azole-refractory C. albicans esophagitis in a patient with autoimmune polyglandular syndrome type 1. Both achieved rapid clinical response and microbiological clearance. These are the first documented cases of rezafungin use for invasive candidiasis in Brazil.
