Abstract

症例は56歳女性.主訴は下痢,嘔気.腹部USで左下腹部に内部に結節をともなう巨大な多房性嚢胞性病変を認め,CT, MRIでは結節部に造影効果を有し後腹膜原発の粘液性嚢胞腺癌と診断した.術中に腫瘍周囲に播種を疑う多数の小結節を認めたが,小結節を含め左半結腸切除術を施行した.病理組織学的には,嚢胞内に粘液が貯留し,充実部は低分化型腺癌であった.結節の上皮下には卵巣様間質を認め粘液性嚢胞腺癌と最終診断した.<br>

We encountered a case of primary retroperitoneal mucinous cystadenocarcinoma with ovarian-type stroma, an extremely rare condition. The patient was a 56-year-old woman with complaints of diarrhea, nausea, and abdominal fullness. Abdominal ultrasound revealed a nodular multi-cystic mass in the left lower quadrant of the abdomen. Subsequent contrast-enhanced CT and MRI determined it to be of retroperitoneal origin, consistent with a mucinous cystadenocarcinoma. Numerous small nodules were confirmed during the operation around the tumor suggesting local dissemination of the cancer and a left partial colectomy that included these nodules was performed. On histological examination, mucinous fluid was found trapped inside the cavity and poorly differentiated adenocarcinoma was observed in the solid portions. The ovarian-type stroma was confirmed in the layer beneath the epithelial lining and eventually a final diagnosis of mucinous cystadenocarcinoma was reached.<br>
