Candida pneumonia in a case of polymyositis complicated with interstitial pneumonitis

We report a polymyositis patient who developed Candida pneumonia, whose clinical manifestations such as dry cough, dyspnea, fever and elevated LDH looked like a recurrence of interstitial pneumonitis (IP) which she had had at admission. The distribution of the lesions in high resolution computed tomography scan, the high serum level of β-D-glucan and positive Candida antigen test led to make a diagnosis of Candida pneumonia rather than IP, and fluconazole therapy was successful.
