Abstract

症例は67歳の男性.健診時の胸部X線検査で左肺腫瘤影を指摘され,治療目的で入院となった.胸部CT検査で左肺腫瘍を疑い,気管支鏡検査を行ったが,確定診断を得られなかったため胸腔鏡下肺生検を施行した.胸腔内を検索すると,肺内病変はなく心膜前脂肪組織上に腫瘤上浮遊物質を認めこれを摘出した.腫瘤は色調白色,大きさ1.7×1.5×1.0cmで,弾性硬であった.病理組織所見では,一部壊死性変化を呈する脂肪組織が本体をなし,その表面は層状の硝子化した結合組織で覆われていた.したがって腫瘤を胸腔内結石と診断した.本症は,本邦報告例として5例を数えるのみで非常に稀であり,文献的考察を加え報告する.

A 67-year-old man was admitted to the hospital for treatment because he was pointed out a tumorous shadow in the left lung on a chest x-ray film at a medical checkup. On a chest CT scan, a left lung tumor was suspected. Since a bronchoscopic study failed to make the definite diagnosis, a thoracoscopy-aided pulmonary biopsy was made. Exploration of the thoracic cavity showed no lesion in the lung, but a tumorous suspending material was seen on prepericardiac fatty tissue and then it was removed. The removed tumor was white in color, 1.7×1.5×1.0cm in diameter, and elastic hard. Histopathologically, the tumor was mainly composed of fatty tissue with a part presenting necrotic change, of which surface was covered with lamellar hyalinized connective tissue. Consequently, the tumor was diagnosed as intrathoracic stone.<br> This disease is so rare that only five cases have been reported in Japan. This rare case is presented here, together with some bibliographical comments.
