Aneurysmal bone cyst of the rib. Robotic resection of a rare lesion.

Primary chest wall tumors are rare, with rib involvement accounting for 5%-7% of primary bone tumors. Aneurysmal bone cysts typically present as a rapidly growing, destructive mass that may infiltrate surrounding tissues. We present the case of a 21-year-old female with chronic pain in the left hemithorax caused by an aneurysmal bone cyst originating from the seventh rib arch. A minimally invasive en bloc resection was successfully performed using a robotic platform. Robot-assisted surgery offers a promising therapeutic approach for patients with well-defined chest wall tumors, allowing for a less invasive procedure and avoiding the need for more extensive techniques that may increase morbidity or necessitate chest wall reconstruction.
