[Invasive sinusal mycosis due to Chrysosporium tropicum].

An invasive sinusal mycosis in a patient with acquired immunodeficiency is reported. The clinical course and causal agent (Chrysosporium tropicum) were both rather atypical. This fungus has been seldom isolated as a cause of nasosinusal infections. Just one more case like this is found when literature is reviewed. We emphasize importance of early diagnosis and treatment to reduce morbi-mortality.
