Posterior Mediastinal Desmoid Tumor Suspected to be a Neurogenic Tumor Before Surgery：Report of a Case

はじめに　デスモイド腫瘍は腹部に好発するまれな軟部腫瘍であり，その臨床経過は多彩で治療方針は定かでない．われわれは，術前に後縦隔の神経原性腫瘍が疑われ手術を施行し，病理組織でデスモイド腫瘍と診断された症例を経験したので報告する．

A man in his 50s who presented an abnormal shadow on chest X-ray was diagnosed with posterior mediastinal tumor that had grown compared to the previous chest X-ray. Computed tomography showed a 5.7×3.9 cm solid mass with a smooth surface in the posterior mediastinum. A neurogenic tumor was suspected, and the mediastinal tumor was resected through thoracotomy because it was strongly adherent. The postoperative course was good, and he was discharged from the hospital on postoperative day 3. Contrary to preoperative expectations, the tumor was pathologically diagnosed as a desmoid tumor. After 6 months postoperatively without any complications, no recurrence was observed.
