[A case of bronchopulmonary actinomycosis diagnosed by transbronchial biopsy of a bronchial polypoid tumor].
A 32-year-old man with history of dental caries had been coughing up blood-tinged sputum since Jan 2000. Chest radiography and computed tomography (CT) scans revealed a solitary nodule with a peripheral infiltrative shadow in the left S 6. Fiberoptic bronchoscopy was performed, but yielded no significant findings. In April 2000, because the nodule had increased in size, bronchoscopy was performed again, and revealed a white smooth-surfaced polypoid tumor in the left B 6 c. A transbronchial biopsy of the polypoid tumor was performed, and the histological findings show long Grocco-positive hyphae that are visible under sulfur granules. Bronchopulmonary actinomycosis was diagnosed. The solitary nodule with a peripheral infiltrative shadow in the left S 6 was eliminated by antibiotic therapy including ABPC/SBT. ABPC and LVFX. This case is important, because there are few reports concerning diagnosis of bronchopulmonary actinomycosis using transbronchial biopsy of a bronchial polypoid tumor.
