Comparative Study
[Spontaneous pneumothorax in patients with osteosarcoma treated by combined chemotherapy].
A report is presented on 5 cases of pneumothorax which occurred during chemotherapy in patients suffering from osteogenic sarcoma of the extremities. None of them presented radiographically detectable substitutive pulmonary lesions. It was hypothesised that the origin of pneumothorax was the necrosis produced by agents of a pulmonary micrometastasis.
