Popis: A 48 year-old immunocompetent woman, who had a nodular lesion in the neck and a dense infiltrate at the lower lobe of the left lung, presented at the Mycology Unit of Muniz Hospital of Buenos Aires City. The pulmonary infiltrate disappeared spontaneously 3 months later. The histopathological study of the nodular lesion showed capsulated yeasts (mucicarmin and alcian blue positive stains) compatible with Cryptococcus. The mycological study of a new sample, obtained by a nodular puncture, allowed the isolation of yeasts, identified as Cryptococcus gattii (VGII). Latex test for Cryptococcus capsular antigen in serum was positive (1/100). CSF cultures rendered negative results. Fluconazole at a daily dose of 800mg was given during 45 days with partial improvement; as cultures from a new clinical sample were positive for Cryptococcus, the antimycotic was changed to itraconazole 400mg/day for 5 months, with an excellent clinical response.
