Giant Cell Tumor of Bone Presenting as Left Posteromedial Chest Wall Tumor.

Giant cell tumor is a relatively uncommon bone tumor rarely originating from the chest wall. Given its proximity to vital structures in the thoracic cavity, treatment options may be challenging. We report the case of a patient with a giant cell tumor of the posterolateral chest wall with invasion of the thoracic spine treated with neoadjuvant denosumab, followed by surgical resection.
