Actinomycosis is a chronic suppurative infection caused by filamentous Gram-positive bacilli, leading to a purulent discharge due to sulfur granule formation. Thoracic actinomycosis represents around 20% of Actinomyces infections, with endobronchial involvement being fairly uncommon. Pulmonary actinomycosis should be considered in the differential diagnosis of non-resolving lobar pneumonia or a lobar mass suspicious for malignancy on endobronchial biopsy. A case of endobronchial actinomycosis presenting as post-obstructive pneumonia and mimicking right upper lobe endobronchial carcinoma, which was associated with foreign body aspiration, is reported here.
放线菌病是由革兰氏阳性丝状杆菌引起的慢性化脓性感染，因形成硫磺颗粒而导致脓性分泌物排出。胸段放线菌病约占放线菌感染的20%，支气管内受累相当少见。在鉴别诊断无法消退的大叶性肺炎或支气管活检时可疑为恶性的大叶性肿块时，应考虑肺放线菌病。本文报告一例表现为阻塞性肺炎并酷似右上叶支气管内癌的支气管内放线菌病病例，该病例与异物吸入有关。
