Disseminated Saprochaete capitata Fungemia in Acute Myeloid Leukemia: A Case Report and Literature Review From the United Arab Emirates

<i>Saprochaete capitata</i> (formerly <i>Geotrichum capitatum</i>) is a rare fungal pathogen that predominantly affects immunocompromised individuals, particularly those with hematologic malignancies and prolonged neutropenia. We report a rare case of S. capitata fungemia in a 49-year-old male newly diagnosed with acute myeloid leukemia (AML), managed in the United Arab Emirates. Despite prophylactic fluconazole during induction chemotherapy, the patient developed persistent febrile neutropenia. Blood cultures drawn from a peripherally inserted central catheter (PICC) grew yeast, later identified as <i>S. capitata</i> via biochemical profiling and carbohydrate assimilation testing. The isolate was resistant to fluconazole and echinocandins but susceptible to amphotericin B and voriconazole. Combination antifungal therapy with liposomal amphotericin B and voriconazole was initiated, and the PICC line was removed. Follow-up imaging revealed pulmonary consolidation and multiple hypodense lesions in the liver and spleen, consistent with disseminated fungal infection. Despite aggressive antifungal management, the patient developed persistent fungemia, multi-organ failure, and died on hospital day 81. This case underscores the diagnostic complexity, intrinsic antifungal resistance, and high mortality associated with <i>S. capitata</i>, and highlights the need for early species identification, tailored antifungal therapy, and improved fungal diagnostics in the region.
