Abstract
A primary aspergilloma of the lung is rare. Recently, a 42-years-old woman was admitted to our hospital for a coin lesion on the chest X-ray film, that revealed a welldefined mass (3.5 × 2.5×3cm) with a cavity in the right upper lobe. Bronchogram showed the obstruction of Rm, lobi superioris horizontalis. Transbronchial biopsy smears were negative for malignant cell and it's culture failed to yield any significant pathology. Inner surface of the cavity was completely covered with a squamous epithelium and the lumen was not patented to the bronchus. We are interested in this disease in the points of differentiation from a lung cancer with a cavity or cavitary other lung lesions.
