Abstract

Actinomycosis is a rare chronic suppurative infection with the characteristics of external sinus tract formation and sulfur granule containing inflammatory discharge from the lesion. Actinomycosis may involve the lung. pleura, mediastinum and chest wall irrespectively of the anatomic boundaries of thorax structures. Because the clinical presentation of pulmonary actinomycosis resembles pulmonary tuberculosis or lung cancer. the diagnosis of pulmonary actinomycosis is often long delayed without telltale draining sinus. And because actinomycosis is a normal flora of oral cavity, the iso lati on of actinomyces in sputum is not adequate for the diagnosis of p111monary actinomycosis. so almost all cases of pulmonary actinomycosis are diagnosed after surgical exploration under the impression of lung cancer. But the development of percutaneous needle lung aspiration made it possible to find characteristic Sulfur granules and diagnose pulmonary actinomycosis without surgery. We presented a case of pulmonary actinomycosis which had been diagnosed by percutaneous needle lung aspiration cytology.
