Successful Treatment of Paecilomyces varioti Infection in a Patient with Chronic Granulomatous Disease and a Review of Paecilomyces Species Infections

An 8-year-old boy who had chronic granulomatous disease developed a soft tissue infection of the right heel after riding on a motor scooter. Infection was insidious, and minor heel pain and fevers occurred only on the day interferon-γ was injected. Soft tissue biopsy showed hyphal elements, and Paecilomyces varioti</it> grew in culture. The infection was treated with amphotericin B for 7 weeks (total dose, 40 mg/kg) followed by 1 year of therapy with itraconazole (100 mg twice daily). Complete cure was achieved during the follow-up period of 10 months.
