Tratamiento exitoso de una mucormicosis rinocerebral persistente en un paciente pediátrico durante el debut de una leucemia aguda

Abstract

The fungi of the order Mucorales cause mucormycosis, which usually presents as an invasive fungal disease with rapid angioinvasion in immunocompromised patients. Rhinocerebral is the most common presentation. The lipid formulations of amphotericin B are used as primary treatment in invasive mucormycosis; the combined use of posaconazole could allow a reduction in the dose of amphotericin B improving tolerance and adherence to treatment. Caspofungin and amphotericin B association has been shown to be synergistic in vitro and effective in murine models. We present the case of a preschool patient that during the debut of acute lymphoblastic leukemia developed a rhinocerebral mucormycosis successfully responding to antifungal treatment with the combination of liposomal amphotericin and caspofungin.
