Behind the Façade: Robotic-Assisted Resection of a Diaphragmatic Osteochondroma

Neoplasms arising from the diaphragm are not typically seen in clinical practice, though they may inflict significant morbidity and mortality. In the realm of thoracic surgery, osteochondromas are only encountered at the thoracic wall or vertebra. In this study, we describe a case of an osteochondroma arising from the diaphragm masquerading as a malignant lesion. The tumor was resected via robotic-assisted means and the patient was discharged with no complications.
