Tumors of the chest wall in infants and children.

Chest wall tumors of children may arise from subcutaneous tissues, the bony thorax, or extrapleural region. Review of experience at our institution and the literature indicates that primary bony tumors are most often malignant; Ewing's sarcoma is the most frequent in this category. Extrapleural tumors are rare but also usually malignant. Clinical and roentgen features of these lesions are discussed.
