胸壁切除および再建を行ったデスモイド腫瘍の1例

Resection of a Chest Wall Desmoid Tumor with Chest Wall Reconstruction；Report of a Case

デスモイド腫瘍は骨格筋や筋膜から発生する良性の線維増殖性腫瘍であるが，浸潤傾向が強く切除後の局所再発率が高いため，臨床的には悪性腫瘍に類似した経過を辿ることが多い．発生部位は腹部，四肢などが多く，胸壁から発生することはきわめてまれである．今回，胸壁に発生したデスモイド腫瘍の1切除例を経験したので報告する．

A primary desmoid tumor arising from the chest wall is extremely rare. We report the case of a 57-year-old man presenting with a desmoid tumor arising from his chest wall. Chest radiograph at a regular medical checkup indicated an abnormal shadow. By computed tomography-guided biopsy, he was diagnosed as having a desmoid tumor. He underwent right-sided chest wall resection and reconstruction. Desmoid tumor is histopathologically benign tumor, however, they tend to show high rates of local recurrence after surgery. In case of recurrence on unresectable case, radiotherapy or some medical treatment should be chosen as a treatment option.
