Description

Background. Pulmonary actinomycosis is often too difficult to make a definitively diagnose, because it is often necessary to distinguish it from lung cancer, tuberculosis, and fungal infection. Case. A 69-year-old woman was admitted to our hospital because of refractory hemoptysis. Chest computed tomography(CT) revealed a cavity about 1.5cm in diameter with focal bronchiectasis in the right S^6. A white mass was shown in the right B^6ciiβ by an ultra-thin bronchoscope. The definitive diagnosis of pulmonary actinomycosis was made by transbronchial biopsy and bronchial lavage cytology from the biopsy specimen because of detection of sulfur granules and drusen. Although the infiltrative shadow on chest CT had improved after administration of amoxicillin for 9 months, hemosputurn and the cavity on CT has been remained. Therefore operation was performed. The postoperative course has been uneventful with no signs of recurrence. Conclusion. We reported a case of pulmonary actinomycosis with hemoptysis diagnosed by ultra-thin bronchoscopy. Cases of pulmonary actinomycosis with recurrent hemosputum and residual lesion after medication may require surgery.
