A 58-year-old man admitted to hospital because of hemoptysis. Chest X-ray showed a large mass in the right middle lobe. A tumor marker CYFRA was slightly elevated. Despite a detailed examination after admission, no definite diagnosis was made. Lung cancer was suspected and a middle lobectomy was performed. Histopathological specimen of resected lung showed typical "sulfur granule" of actinomycosis. Pulmonary actinomycosis should be included in the differential diagnosis of a pulmonary mass lesion.

We clinically and radiologically examined 8 patients with pulmonary actinomycosis. Their clinical features were slowly progressive, and the most commonly occurring symptom was hemoptysis. Laboratory findings disclosed elevated ESRs, a sign of chronic inflammation. Roentgenographic films showed a higher percentage of lesions in the right lung and on the dorsal side. On chest CT images, the lesions appeared as nodular or consolidated shadows with atelectasis, and spread widely over the parietal pleura in the periphery of the lung fields. The margins of the nodules were irregular, and multiple blood vessels were involved. The internal density of the nodules contained either a low attenuation region or cavity. In relation to the pleural, local pleural thickening adjacent to the nodules was identified in all patients, and the thickened areas were thin and smooth. Although it was difficult to diagnose by transbronchial lung biopsy (TBLB), granulation tissue obtained by TBLB was considered an important finding suggestive of pulmonary actinomycosis. As diagnostic procedures, repeated TBLBs appear to be effective for lesions extending into the hilar region, and video-assisted thoracoscopic surgery, for small nodular lesions located in the periphery of the lung fields.

Pulmonary actinomycosis is a chronic pulmonary infection caused by Actinomyces, a Gram-positive, microaerophilic bacterium. Pulmonary involvement, other than cervicofacially or abdominopelvically, is uncommon and often leads to a misdiagnosis of pulmonary tuberculosis or lung cancer. In order to investigate the clinical, radiological, diagnostic and therapeutic characteristics of pulmonary actinomycosis, we reviewed a total of 25 cases reported in Korea. Thirteen were diagnosed at our hospital between 1985 and 1997 and 12 were reported in Korean publications. The condition occurred most frequently in middle-aged males, the most common symptom being haemoptysis, followed by cough and sputum. The main radiological features were peripherally located mass or nodule and consolidation, with central low attenuation. Complications such as empyema, sinus fistula or mediastinitis did not occur. Diagnosis was confirmed by percutaneous needle aspiration (n = 8), bronchoscopic biopsy (n = 3) or thoracotomy (n = 13). Eleven of 25 cases were treated medically and in nine others, surgical resection was followed by treatment with antibiotics. In conclusion, when a middle-aged male patient presents with haemoptysis and cough, together with radiologic findings of a peripheral mass or nodule with/without central low attenuation, pulmonary actinomycosis should be suspected.

Thoracic actinomycosis is a rare disease often mistaken for malignancy. Untreated actinomycosis is associated with high mortality, the disease should, thus, be considered early. We report the case of a 58-year-old male patient who was referred to us for a suspected thoracic sarcoma. He had 6-month a history of hemoptysis, and there was severe deterioration in his general health. Only in a roundabout way was the diagnosis of thoracic actinomycosis established; it was caused by an aspirated chicken bone, as found by bronchoscopy. All symptoms rapidly regressed by antibiotic therapy and definitive healing was obtained. In the diagnostic work up of thoracic masses that may represent inflammatory diseases, lymphoma, thymus-associated, sarcomatous and germ-cell tumors, bronchoscopy is of primary diagnostic importance.

Actinomycosis is a relatively rare infection. This is a report of 16 patients with pulmonary actinomycosis diagnosed from 1990 to 1997 at the Central Chest Hospital, Thailand. Twelve patients were male and 4 were female, with a mean age of 59 years and a mean duration of symptoms of 9 months. Common symptoms were cough and hemoptysis. Mass-like shadowing was the most common radiographic finding (37%). The diagnosis, based on findings of typical sulfur granules, was reached by bronchoscopy (10 cases), surgery (5 cases) and fine needle aspiration (1 case). Endobronchial mass with luminal occlusion was the most frequent bronchoscopic finding (56%). Coexistent bronchial carcinoma was present in one specimen. Penicillin was given in 10 patients, 2 of whom (20%) were cured, 5 (50%) are currently on treatment and have achieved clinical response, whereas, the other 2 patients (20%) did not respond. Surgical resection was performed in 8 patients, all of whom recovered. An awareness of the full spectrum of actinomycosis manifestations will expedite diagnosis and optimize treatment.

A 59-year-old male clerk consulted in general practitioner due to cough and hemoptysis. A mass shadow was pointed out in the left upper lung field on a chest radiograph. Patient was referred to our hospital for further treatment. Any definitive daiagnosis could not be made after examinations including sputum culture, cytology and TBLB. Because a lung cancer was strongly suspected, an exploratory thoracotomy was performed. Actinomyces was detected by pathological study of excised specimen, with no evidence of cancer. ABPC was administered for two months postoperatively. The patient is doing well without recurrence of actinomycosis 2.5 years after the surgery. Pulmonary actinomycosis presenting a mass shadow on a radiograph may mimick a pulmonary tumor, especially a lung cancer. Pulmonary actinomycosis should be considered in a differential diagnosis of pulmonary lesion thought to be malignant.

We report a case of pulmonary suppuration due to a mixed infection of anaerobic bacterium and Actimomyces. A 49-year-old man was admitted to our hospital because of hemoptysis on March 30, 1999. A chest X-ray film showed a localized shadow in the right middle lobe, and a tumor shadow was recognized on chest CT. The anaerobic bacterium were isolated from specimens collected bronchofiberscopically. A diagnosis of pulmonary suppuration due to anaerobic bacterium was made, and treatment with sulbactam/ampicillin, followed by imipenem/cilastatin, was initiated. Although his clinical symptoms and laboratory data improved rapidly following this treatment, the abnormal finding on the chest radiographs remained, with only slight improvement. Accordingly, surgical resection of part of the right middle lobe was performed on June 29 using a video-associated thoracic surgery technique. Actinomycosis was recognized by pathological examination of the resected lesion. A revised diagnosis of pulmonary suppuration due to a mixed infection of anaerobic bacterium and Actinomyces was made. Anaerobic bacterium in the oral cavity are recognized as significant pathogens in pulmonary suppuration. In the present case, we considered anaerobic bacterium and Actinomyces aspirated from the oral cavity into the lung to have caused the pulmonary suppuration.

The patient was a 58-year-old man who had been admitted in 1995 because of hemoptysis. Chest CT scans showed air-space consolidation with dilated bronchi and calcification in the right S3. He received a diagnosis of bronchiectasis with old tuberculosis. Bronchial arteriography showed arterialization in the right S3, and bronchial artery embolization was performed. But in 1996 hemoptysis reappeared. He was readmitted in May 1999 because of recurrent hemoptysis. Bronchial arteriography showed recurrence of arterialization in the same area, and chest CT scans showed growth of the mass shadow. Right upper lobectomy was performed, and the microscopic findings of the resected specimen showed sulfur granules in the dilated bronchus. We concluded that pulmonary actinomycosis should be considered in the differential diagnosis of abnormal chest shadows.

Actinomycosis is a slowly progressive infectious disease caused by an anaerobic and microaerophilic bacteria that colonizes the face, neck, lung, pleura and the ileocecal region. There have been a few cases of this disease which have involved in the lung but one very rare case has been reported. We report a case of foreign body-induced endobronchial actinomycosis mimicking bronchogenic carcinoma in a 69-year-old man. On admission, the patient presented with weight loss, cough and hemoptysis. The fiberoptic bronchoscopy revealed a soft tissue mass, with a partial occlusion of the left upper bronchus, which resembled bronchogenic carcinoma. Contrary to the first impression, the biopsy of the bronchus revealed the mass lesion to be an actinomycotic infection involving the bronchus. After the confirmation of the lesion, treatment with penicillin was initiated. The follow-up bronchoscopy revealed an aspirated fish bone at the site of infection. The foreign body was safely removed.

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.
