Cryptococcus laurentii lung abscess.

Pulmonary infection with Cryptococcus laurentii occurred in a patient with dermatomyositis receiving corticosteroid therapy. Infections with cryptococci other than C. neoformans are rare, and pulmonary involvement with C. laurentii has not been reported previously. The isolate was susceptible to amphotericin B but resistant to 5-fluorocytosine, and synergism could not be demonstrated with these 2 drugs. Amphotericin B without surgical resection, concurrent with reduction in the dosage of corticosteroids, resulted in clinical and roentgenogrphic resolution of the infection.
