AbstractWe report the first case of primary pulmonary sporotrichosis in Japan. A 53-year-old man was admitted to our hospital for further examination of the abnormal shadows on chest X-ray film. Six months before admission, he was admitted to another hospital because of alcoholic liver disease and diabetes mellitus. Since the initial chest film showed cavities with infiltration in the left upper lung field, he was treated with antituberculous drugs despite negative sputum cultures for mycobacterium. In spite of the medication, his chest X-ray film revealed another cavitary lesion, so he was referred to our hospital. He had been asymptomatic during this period. Chest X-ray on admission disclosed multiple cavities in the left upper lobe and a cavity in the right lower lobe. Repeated sputum specimens, bronchial washings and brushings for cytology and cultures were all negative. In an attempt to clarify the pathogen, percutaneous lung aspiration (PLA) was performed. The PLA sample yielded a positive culture of Sporothrix shenckii. After the diagnosis, S. schenckii was also cultured from sputa. A sporothrix skin test and yeast agglutination test for S. schenckii were positive. In the absence of a history for skin lesion, the patient was diagnosed as a primary pulmonary sporotrichosis. As iodide therapy was ineffective, he was started on a regimen of intravenous amphotericin B. However his renal function progressively deteriorated, so amphotericin B was discontinued. Now he receives miconazole intravenously and is still under careful observation. As far as we know, this is the first report of primary pulmonary sporotrichosis in Japan. The possibility of sporotrichosis should be considered in any cases of undiagnosed cavitary lung diseases.
