[A case of primary pulmonary cryptococcosis showing spontaneous recovery].

A 37-year-old woman was admitted with fever and cough. The chest roentgenogram revealed a solitary large round mass in the right lower lung field. Diagnosis was made by transbronchial lung biopsy. There was no evidence of abnormal cell-mediated immunity. The patient made an uneventful recovery and the chest X-ray showed progressive clearing without specific therapy. After 6 months, the mass lesion disappeared. This case suggests that specific therapy may not be necessary for all cases of primary pulmonary cryptococcosis.
