[Favorable outcome of orbital nasal sinus mucormycosis complicating the induction treatment of acute lymphoblastic leukemia].
BACKGROUND
Most cases of mucormycosis occur in immunosuppressed children. Intracranial extension is lethal and must be prevented with early specific treatment.


METHODS
A 42 month-old boy was admitted suffering from acute lymphoblastic leukemia. Edema of the left eyelid developed on the sixth day of induction chemotherapy. Mucormycosis was suspected because of gradual extension of infection to nasal ala and periorbital area with fever, edema of nasal turbinates and nasal black secretions. Chemotherapy was discontinued and the patient was given intravenous amphotericin B (1.0 mg/kg/day) and heparin associated with G.CSF. Improvement was only temporary and scan examination performed on day 17 showed involvement of the orbit, eye and wall of the maxillary sinus; cultures of secretions were positive for staphylococcus and Absidia corymbifera. Remission of leukemia was obtained a few days later permitting surgical resection of involved tissues on day 30. A relapse of mucormycosis was observed six weeks later despite prolonged administration of amphotericin B requiring extended resection of necrotic areas and replacement of amphotericin B by its liposomal form (Ambisome). Bone marrow relapse of leukemia required further chemotherapy. The patient is in good condition 30 months after the initial symptoms.


CONCLUSIONS
Our patient seems to be the first with prolonged remission of facial mucormycosis and acute leukemia despite relapse of both diseases. This favorable outcome could be due to the use of Ambisome.
