Key result
Surgical resection via median sternotomy was performed for a massive mediastinal liposarcoma in a 64-year-old man, with tumor recurrence observed 4 months postoperatively.

No
Surgical resection of a massive mediastinal liposarcoma is feasible, but the pleomorphic subtype carries a poor prognosis with early local recurrence.
Early recurrence after resection signals poor prognosis in pleomorphic mediastinal liposarcoma; leaves open optimal multimodal strategies for future cases.
症例は67歳，男性．高血圧にて近医経過観察中に心窩部不快感出現．超音波検査，胸部レントゲンにて右中～下肺野に超手拳大の腫瘤を指摘され当院紹介となった．CTにて右胸腔～縦隔右側にかけて160×110mmの腫瘤を認めた．腫瘤は上大静脈，右房を圧排し，心膜，横隔膜への浸潤も疑われた．CTガイド下生検施行しspindle cell sarcomaの診断で手術が施行された．左側臥位にて審査胸腔鏡施行後，摘除可能と判断し，仰臥位，胸骨正中切開にて摘出術施行した．術後経過は良好で，第15病日に退院となった．術後病理検査にて脂肪肉腫と診断された．今回比較的まれな縦隔発生の脂肪肉腫の1手術症例を経験したので報告する．
