Robotic resection of a second rib osteochondroma.

A 43-year-old man presented with a several-month history of worsening left shoulder pain. On imaging, he was found to have an osseous mass arising from his left second rib and protruding into the soft tissues of his chest. The mass had radiographic characteristics consistent with those of an osteochondroma. He had point tenderness over the mass, and the area of point tenderness was consistent with his description of the location of his pain over the past several months. Based on his symptoms, he was taken to the operating room for robotic excision of this mass. He was placed in a right lateral decubitus position, and three robotic ports were inserted. The mass was identified based on landmarks and was dissected free. The bony attachment of the mass to the second rib was transected using a Kerrison rongeur. The mass was delivered into the chest and removed using an endobag. The patient was discharged the following day after removal of his Blake drain. His pain had completely resolved at the postoperative follow-up examination, and his final pathological report confirmed the benign diagnosis of osteochondroma.
