Abstract:
A case of thoracic mass infiltrating the chest wall mimicking a pulmonary invasive neoplasm is reported. Differential diagnosis and characteristic radiological and histological imaging had a decisive role in the case management. Actinomycosis is caused by a gram-positive, filamentous, microaerophilic bacteria. About 15% of the infections caused by Actinomyces involve the thorax. If not promptly diagnosed and treated thoracic actinomycosis may determine contiguous and systemic involvement. Actinomycosis is an anaerobic-to-microaerophilic bacteria and direct identification and isolation are difficult to obtain. In depth discussion diagnostic and therapeutic features are described in this report.

Clinical Manifestations:
Muscles of the Thorax
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It originates...

The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid process.
