Abstract
A 6-year-old boy with chronic granulomatous disease was admitted to our hospital due to a fever, cough and dyspnea. Diagnosis of mycoplasmal pneumonia was established on the basis of rising titer of specific antibody. The patient was treated with MIND, SMX-TMP, Amphotericin-B, Pentamizin and CEX. Although his clinical course was severe and complicated as compared with that of an underlying disease, the patient recovered and was discharged on the 30 th day following the onset of his illness.
