Rhinocerebral mucormycosis in a boy with recurrent acute lymphoblastic leukemia: Long-term survival with systemic antifungal treatment

Rhinocerebral mucormycosis is rare in hematologic malignancies and usually leads to death within weeks. In contrast, chronic rhinocerebral mucormycosis takes a slowly progressive course and has not been reported in hematologic malignancies in children so far. The authors report the long-term survival of a boy with rhinocerebral mucormycosis in a relapse of acute lymphoblastic leukemia after allogeneic cord blood transplantation. The disease started acutely but took a chronic course thereafter. No surgical debridement was performed because of extensive involvement of the sinuses, orbits, and cerebrum. His long-term survival of 15 months is attributed to the long-range administration of liposomal amphotericin B, early neutrophil recovery, and slow progression of the relapsing acute lymphoblastic leukemia.
