We report about two cases of tumor dissemination after thoracoscopic w
edge resection of malignant nodules of the lung. In the first case, a
metastasis at the extraction site was observed after thoracoscopic res
ection of a metastasis of the lung. In the second case we diagnosed a
pleural carcinosis after thoracoscopic wedge resection (and additional
open lobectomy and lymph node dissection) of a pT2 NO lung cancer. Th
e patient died 12 months after the operation. The indication for thora
coscopic resection of malignant nodules of the lung should be restrict
ed for peripheral tumors smaller than 2 centimetres.
