Pulmonary actinomycosis is rare, but its diagnosis is changing due to its variable presentation; the similarity in appearance to other intrapulmonary diseases. Here we report an 80-year-old man with a solitary pulmonary nodule over the left upper lobe. Pulmonary neoplasm was highly suspected in this patient; thus resection of the mass was undertaken through video-assisted thoracic surgery (VATS). Histopathological examination demonstrated this patient had an Actinomyeces infection. While the application of VATS in patients with pulmonary actinomycosis has rarely been reported in literature, we conclude that VATS is valuable for the diagnosis; treatment of patients with undetermined pulmonary nodule(s).展开更多

Aside from cervicofacial or abdominopelvic actinomycosis, pulmonary involvement is rare, and sometimes this type of infection results in a misdiagnosis of pulmonary tuberculosis or carcinoma. Clinical presentation of pulmonary actinomycosis could be acute or subacute, with lobar involvement. However, the disease is most commonly diagnosed at the chronic phase, with patients presenting mild fever, weight loss, and occasional hemoptysis. Here, we described the case of a 30-year-old male patient, presented with a history of respiratory complaints for more than three years and was diagnosed clinically and radiologically as a case of a destroyed left lung. Later on, post-operative tissue diagnosis was confirmed—pulmonary actinomycosis.展开更多

Actinomyces israelii is usually responsible for the infections and causes chronic suppurative and granulomatous infections. The most common disease form is cervicofascial infection. Liver is involved in 5% of all actinomycosis infections. Liver involvement secondary to any primary infection site in the abdomen frequently occurs. In 15% of abdominal infections the liver is also involved. However, in very rare cases, a primary focus cannot be found, and these cases are called primary or isolated hepatic actinomycosis （IHA）. IHA which is frequently seen as a solitary abscess can be confused with a malignancy both clinically and radiologically.展开更多
