Curvularia species are ubiquitous and occasionally lead to infections in humans. In immunosuppressed patients, infections are often serious, and systemic dissemination is not uncommon. The optimal antifungal therapy is unclear. I here present two cases, a healthy man with locally invasive, mulicentric paranasal fungal sinusitis, and a case of progressive verrucal distal onychomycosis that developed while the patient was undergoing accelerated chemotherapy for non-Hodgkin's lymphoma. Both patients showed excellent responses to treatment with itraconazole suspension. Oral itraconazole may provide a safe and effective alternative for patients with locally invasive non-disseminated mycoses due to Curvularia species.
