エホバの証人信者の心臓横紋筋肉腫に対する手術の1例

Surgery for Cardiac Rhabdomyosarcoma in Jehovah’s Witnesses：Report of a Case

はじめに　心臓横紋筋肉腫はきわめてまれな心臓悪性腫瘍で，その術後成績も不良と報告されている．われわれは乳癌術後の定期CTで偶発的に左房内腫瘍を認めたエホバの証人信者の症例に対して腫瘍摘出術・僧帽弁置換術を施行し，病理検査で左房原発横紋筋肉腫と診断された症例を経験した．文献的考察を加え報告する．

Primary cardiac malignant neoplasms are rare, and rhabdomyosarcoma is the second most common cardiac sarcoma. We herein report a rare case of 70-year-old female with a cardiac rhabdomyosarcoma in the posterior wall of the left atrium. She was a member of Jehovah’s Witnesses. We performed surgical tumor resection and mitral valve replacement because of apparent tumor invasion to the posterior leaflet of the mitral valve without blood transfusion. Postoperative course was uneventful and she was scheduled to undergo proton beam therapy. This is the first case report of surgically treated cardiac rhabdomyosarcoma in a Jehovah’s Witness.
