Successful treatment of disseminated cryptococcal infection in a pediatric acute lymphoblastic leukemia patient during induction.

Disseminated cryptococcal infection is rarely reported in the setting of pediatric acute leukemia, despite the immunocompromised state of these patients. However, when present, disseminated cryptococcal infection poses treatment challenges and is associated with significant morbidity and mortality. Treatment of invasive fungal disease in a child with acute leukemia requires a delicate balance between antifungal and antineoplastic therapy. This balance is particularly important early in the course of leukemia, as both the underlying disease and overwhelming infection can be life threatening. We describe the successful management of life-threatening disseminated cryptococcosis in a child with acute lymphoblastic leukemia during induction therapy.
