Fluconazole in the treatment of pulmonary zygomycosis

Pulmonary zygomycosis is an aggressive, often terminal infection that may be found in patients who are immunocompromised as a result of cytotoxic chemotherapy. Conventional treatment is by surgical debridement augmented with high-dose intravenous amphotericin B, but even with such treatment the course is usually fulminant with a high mortality rate. Recent work has suggested that the new antifungal triazole, fluconazole, may be of benefit in treating zygomycete infection. The case of a 15-year-old boy who developed pulmonary zygomycosis while on chemotherapy for acute lymphoblastic leukaemia, and who survived for 11 months with oral fluconazole therapy alone, is supportive of this proposal.
