[Spontaneous resolution of primary pulmonary cryptococcosis]

A 22-year-old man underwent chest roentgenography to obtain a health certificate, and the film showed a nodular lesion in the left lung. Computed tomography of the chest revealed a 25 x 20 mm nodular lesion in the S4 segment of the left lung. Fiberoptic bronchoscopy was done and transbronchial biopsy specimens showed fungal elements consistent with Cryptococcus. Further examinations, including cereberospinal fluid examination, were negative. This patient's pulmonary cryptococcal lesion resolved without treatment and without complications.
