Actinomycosis is a subacute and chronic disease. It easily forms external sinuses, especially with cervcofascial involvement. However, thoracic involvement without fistula formation, or with invasion to the liver, is rare.
We report a 53-year-old man with thoracie actinomycosis. He was referred to
our hospital with a lesion in the left lower lobe of the lung that involved
the chest wall. Computed tomography (CT) of the chest revealed a lung tumor of the left lower lobe in contact with the chest wall, diaphragm, and liver. Preoperative study, including CT-guided biopsy, did not disclose any definite diagnosis. An exploratory thoracotomy revealed a huge tumor in the periphery of the lower lobe of the left lung with invasion to the chest wall, diaphragm and the lateral segment of the liver. The tumor was resected and actinomycosis was proved by pathological examination. Postoperative course was uneventful, and the patient was given penicillin for 6 weeks, with no signs of recurrence at the time of the latest (1 year) follow-up. |
