極めて稀な胸壁原発の血管周皮細胞腫の1例を経験した.症例は46歳の女性で右背部痛を主訴に近医を受診した.右胸壁腫瘤を指摘され,当科を紹介された.胸部CTで右上肺野に大きさ2.0×2.0cmの胸膜外腫瘤を認め,手術を施行した.第5肋間で開胸し,被膜に覆われた拇指頭大,弾性軟の腫瘤を第4,第5肋骨とともに指出した.術後の病理組織学検査の結果は血管周皮細胞腫であった.術後経過は良好で,術後7カ月目の現在,再発の兆候は見られていない.血管周皮細胞腫は血管の周皮細胞から発生する血管系腫瘍のひとつで,病理組織学的に悪性所見が乏しくても,再発や転移の頻度が高い.一般に,本疾患は下肢軟部組織,特に大腿,骨盤窩後腹膜に発生し,胸壁に原発することは極めて稀である.胸壁原発の血管周皮細胞腫について若干の文献的考察を加え報告する.

An extremely rare case of primary hemangiopericytoma of the chest wall is reported. A 46-year-old female was admitted to the hospital because of a right back pain. An extrapleural tumor of 2.0×2.0cm in size was detected by the chest computerized tomography (CT) scanning. The tumor was excised with a part of the 4th and 5th ribs. The pathohistological diagnosis was low-grade malignant hemangiopericytoma. Tumor cells were immunostained positively only to vimentin. The postoperative course was unevenful. The patient is now doing well as of 7 months after the operation. Hemangiopericytomy is a vascular tumor in which pericytic cells of vessel walls proliferate. It often recurs or metastasizes in spite of its benign histopathological feature. So careful follow up is important. It commonly occurs in the soft tisues of the lower extremities, especially in the thigh, perive cavity, and retroperitoneum, and rarely in the chest wall. This paper also describes a review of hemangiopericytoma arising of the chest wall seen in the Japanese literature.
