We present two cases of spontaneous pneumothorax secondary to metastatic synovial cell sarcoma. Radiographic techniques initially did not suggest lung nodules in either patients; thoracoscopy allowed sequential bilateral detection of small pulmonary metastases in one case and confirmed the diagnosis during treatment of recurrent pneumothorax in the second case. This report underlines that pneumothorax may be the first clinical manifestation of metastatic sarcoma and can occur even if current imaging techniques are not indicative of metastatic disease. In the latter instance, thoracoscopic exploration has to be envisaged in order to rule out the possibility of metastatic lung involvement.
我们报告了两例继发于转移性滑膜细胞肉瘤的自发性气胸病例。最初的影像学检查未提示任何一例患者存在肺结节；在其中一例中，胸腔镜检查依次双侧发现了小的肺转移灶，在另一例中，胸腔镜检查在复发性气胸治疗期间确诊了病情。本报告强调，气胸可能是转移性肉瘤的首个临床表现，即使当前的影像学技术未提示存在转移性疾病时也可能发生。在后一种情况下，必须考虑进行胸腔镜探查以排除肺转移的可能性。
