[Disseminated fungal infection due to Magnusiomyces capitatus in a liver graft patient]. / Infection fongique disséminée à Magnusiomyces capitatus chez un patient transplanté hépatique.

Disseminated fungal infections due to Magnusiomyces capitatus are rare, occurring exclusively in immunocompromised patients. We report the first case in a liver transplant patient with chronic rejection and portal thrombosis who had a M. capitatus fungemia with a refractory septic shock. Despite an antibacterial and antifungal treatment with caspofungin empirical treatment, the patient died from multiple organ failure. Subsequently, mycological examinations of blood cultures, bronchoalveolar lavage fluid and urine were positive to M. capitatus identified by mass spectrometry and confirmed by sequencing respectively. The stain was resistant to caspofungin and fluconazole. The best treatment appears to be the combination of amphotericin B and voriconazole or amphotericin B and 5 fluorocytosine.
