Invasive fungal infection is among the leading causes of morbidity, mortality, and economic
burden for patients with acute leukemia after induction of chemotherapy. In the past few decades, the
incidence of invasive fungal infection has increased dramatically. Its management has been further
complicated by the increasing frequency of infection by non-Aspergillus molds (e.g. Mucorales). Neutropenic
patients are at a high risk of developing an invasive mucormycosis with fulminant course and
high mortality rate (35–100%).
We are presenting the case of a 72-year-old male with an acute monoblastic leukemia.
The patient was treated during five days with hydroxycarbamide 2 × 500 mg/day, followed by cytarabine
2 × 20 mg/sc over the next 10 days. He developed febrile neutropenia, headache, and edema of
the right orbital region of the face. Computed tomography of the sinuses revealed shadow in sinuses
with thickening of mucosa of the right paranasal sinuses. Lavage and aspirate from the sinuses revealed
Rhizopus oryzae. Mucormycosis was successfully treated with amphotericin B (5 mg/kg/day) followed by
ketoconazole (400 mg/day). Two months later the patient died from primary disease.
In patients with acute leukemia who developed aplasia, febrile neutropenia, and pain in
paranasal sinuses, fungal infection should be taken into consideration. New and non-invasive methods for
taking samples from sinuses should be standardized in order to establish an early and accurate diagnosis
of mucormycosis with the source in paranasal sinuses, and to start early treatment by a proper antifungal
drug. Clear communication between physician and mycologist is critical to ensure proper and timely
sampling of lavage and aspirate from sinuses and correct specimen processing when mucormycosis is
suspected clinically.
