Abstract Chondrosarcomas are the most frequently occurring primary malignant chest wall tumors. Furthermore, the lungs serve as the most frequent sites for metastases. Pulmonary metastases from sarcomas usually appear as round nodules of varying sizes on roentgenograms. Here, we report an unusual clinical and radiographic presentation of pulmonary metastasis from a costal chondrosarcoma. Bilateral pulmonary metastases developed soon after wide surgical resection. Thoracic computed tomography revealed unusual radiological findings: consolidation accompanied with ground-glass opacity. To confirm the metastasis, we recommend a transbronchial biopsy in cases where unusual pulmonary findings are detected. Background Chondrosarcomas are the second most frequent primary malignant bone tumors, after osteosarcomas [1,2]. They are also the most common primary malignant chest wall tumors: 5-15% of chondrosarcomas are located in the thoracic wall [3]. Since radiotherapy and chemotherapy are generally ineffective against chondrosarcomas, surgery is the only curative treatment, and the quality of the surgery is an essential prognostic factor [2]. Enneking et al. classified surgical margins into wide, marginal, and intralesional [4]. A wide resection is accomplished by a procedure in which the lesion, its pseudocapsule and/or reactive zone, and a surrounding cuff of normal tissue are taken as a single block. Therefore, resection for chest wall chondrosarcoma should be wide, taking intact pleura internally, intact muscle fascia externally, and transverse rib resection > 2 cm from the tumor on both directions [4,5]. Clinically, the involved rib en bloc * Correspondence: [email protected] 1 Department of Orthopedic Surgery, Osaka Medical Center for Cancer and Cardiovascular Diseases, Osaka 537-8511, Japan Full list of author information is available at the end of the article
should be resected along with the 2 intercostal spaces above and below the tumor. On roentgenograms, pulmonary metastases usually appear as multiple peripheral, round nodules of varying sizes. Here, we describe an atypical presentation of pulmonary metastasis occurring soon after wide surgical resection of a costal chondrosarcoma. In this case, a thoracic computed tomography (CT) scan showed consolida
