Chest wall tumors in infants and children

Abstract

Chest wall tumors are infrequent in infants and children, but a high proportion of these tumors are malignant. They present most frequently as a palpable mass, and less frequently with pain or respiratory distress. Radiographic evaluation should include chest radiographs followed by computed tomographic (CT) scan. In most cases an initial incisional biopsy is performed because of the significant risk of malignancy. The most frequent tumors are the malignant small round cell tumors (Ewing's sarcoma/primitive neuroectodermal tumor [PNET] family) followed by rhabdomyosarcoma, osteosarcoma, chondrosarcoma, and a spectrum of other sarcomas. Initial treatment with chemotherapy, particularly for the malignant small round cell tumors and osteosarcoma, may facilitate resection by decreasing the size of the tumor as well as its vascularity and friability. Cure requires successful local control and adjuvant chemotherapy and is particularly difficult to achieve in children presenting with metastases.
