後腹膜嚢胞性中皮腫の1例を報告する.症例は42歳の女性.感冒にて近医を受診した際,下腹部に腫瘤を指摘され,当科紹介入院となった.注腸造影,腹部CTなどの検査にて,後腹膜嚢胞性腫瘤を疑い,開腹術を施行した.手術所見では,下行結腸の後方に単房性嚢胞が存在し,結腸を内方に圧排していた.病理組織学的に,嚢胞の内腔は一層の細胞からなり,組織化学的検討では,ケラチン,コロイド鉄が陽性, CEA,ヒアルロニダーゼが陰性で嚢胞性中皮腫と診断した.<br> 孤立性単房性の後腹膜嚢胞性中皮腫は非常に稀な疾患であるが,腹部嚢胞性腫瘤を認めた場合,嚢胞性中皮腫も鑑別診断のひとつにいれておくべきであると考えられた.

We report a case of retroperitoneal cystic mesothelioma. The patient was a 42-year-old woman with no particular problems in her medical history. She first presented to another hospital becouse of common cold, where an abnormal mass in her lower abdomen was pointed out. Then she was admitted to the hospital. The findings obtained by Computed tomography, ultrasonography and barium enema showed a large cystic tumor probably originated from the retroperitoneum. Laparotomy was performed. Surgical exploration showed that a solitary cystic mass was located behind the descending colon and compressed the colon imward. The postoperative histological findings revealed that the tumor was cystic mesothelioma. This histological classification can be achieved by histochemical and immunohistochemical studies with keratin, colloid-Fc and CEA. Retroperitoneal cystic mesothelioma is not a common disease, however, it should be taken into consideration in the differential diagnosis of abdominal masses.
