BackgroundSpontaneous pneumothorax complicating chemotherapy has been reported mainly in metastatic sarcoma, particularly of the osteogenic type. The main factor in the etiology of spontaneous pneumothorax could be related to tumor lysis and/or rapid rupture of chemosensitive peripheral or subpleural metastasis into the pleural cavity, thus leading to a bronchopleural fistula.Methods And ResultsA 49-year-old patient in whom spontaneous pneumothorax developed after successful chemotherapy for metastatic seminoma is described. On chest tube drainage, the lung reexpanded rapidly and the patient became clinically and radiographically symptom free.ConclusionTo the authors' knowledge, this is only the second case of spontaneous pneumothorax complicating chemotherapy-induced rapid regression of lung and mediastinal metastases in patients with seminoma. Spontaneous pneumothorax should be included in the spectrum of chemotherapy-related side effects in chemosensitive solid tumors with lung metastases.
