thoracic actinomycosis

Thoracic actinomycosis is a chronic bacterial infection affecting the lungs and surrounding structures. It is caused by Actinomyces bacteria, which are normally present in the human body but can become pathogenic when mucous membrane integrity is compromised. This form of actinomycosis typically results from inhaling the organism and can cause symptoms such as weight loss, night sweats, coughing, and high fever.1

Actinomycosis is characterized by the development of abscesses and draining sinus tracts that exude sulfur granules. While rare in humans, it typically affects individuals between 20 and 50 years old. Treatment involves antibiotics, and surgical drainage or excision of accessible lesions may also be beneficial.1
