Poorly controlled long-standing empyema can dissect through soft tissues and skin resulting in empyema necessitans. We present the first reported case of empyema necessitans caused by Mycobacterium xenopi, which was treated successfully with antimycobacterial therapy. The case highlights the indolent nature of the pathogen and the importance of an accurate diagnosis.
