[Paravertebral muscle metastasis from lung cancer; report of a case].

A 69-year-old man had undergone right S6 segmentectomy for lung cancer (poorly differentiated adenocarcinoma, pT2N0M0, stage IB). One years later, computed tomography (CT) showed abnormal shadow in the right paravertebral muscle of 7 x 5 cm in size. The patient underwent resection of the tumor. The tumor was white, solid and elastic hard mass. Histopathologically, the tumor was paravertebral muscle metastasis from lung cancer. The patient was discharged on 23rd postoperative day, but died of other disease after 1 and a half month postoperatively.
