[An operated case report of pulmonary aspergillosis by sapprophytic infection of Aspergillus candidus in congenital bronchial cyst of right lower lobe].

Aspergillosis is a mycotic disease caused by a variety of species of the dimorphic fungus aspergillosis, especially aspergillus fumigatus. But the report of pulmonary aspergillosis by aspergillus candidus is very rare. We experienced a surgical case of pulmonary aspergillosis caused by aspergillus candidus. The patient is a 18-year-old girl. Eleven years ago, she had suffered from pneumonia of rt. lower lobe, there after she often has suffered from cough and fever every year. In 1986, chest x-ray photography shows a small cavity in rt. lower lobe. In 1989, it becomes a big cavity of 8 X 8 cm in diameter with niveau. She has cough and bloody sputum of 100-150 ml daily. We have cultured aspergillus candidus from sputum, bloody pus obtained by percutaneous aspiration needle lung biopsy of the cavity and bloody pus in the cavity which was resected on March 3, 1989. But the pathological investigation could not demonstrate any fungus ball or fungus body of aspergillus candidus.
