肺転移を繰り返す孤立性線維性腫瘍に対する術式

Consideration of Surgical Procedure for Repeated Pulmonary Metastases of Solitary Fibrous Tumor

孤立性線維性腫瘍（SFT）は，間葉系細胞由来のまれな軟部腫瘍である．SFTの多くが良性であり，外科的切除が有効であるが，時に再発・転移がみられる1）．

We report a case of a solitary fibrous tumor with repeated lung metastases after resection of the primary tumor. The patient was a 58-year-old man who had a left upper lobe lung tumor resected in 2018. The tumor was a solitary fibrous tumor arising from the visceral pleura. During the subsequent follow-up, the tumor repeatedly metastasized into the lung, and a total of three surgeries were performed. From the specimen at third surgery, the possibility of the enucleation of the tumor was speculated from the macroscopic and microscopic findings. Since repeated resections of the lung may cause the gradual deterioration of pulmonary function, the possibility of tumor enucleation will be discussed for the future treatment plan.
