Abstract Retroperitoneal mucinous cystadenocarcinomas are extremely rare. A 40-year-old Japanese woman was found to have a retroperitoneal mucinous cystadenocarcinoma of ovarian type. Both ovaries were normal. Concentrations of carcinoembryonic antigen and carbohydrate antigen 19-9 in the cyst fluid were extremely high (810 000 ng/ml and 8 082 000 IU/l, respectively). The tumor varied from benign to borderline and malignant in microscopic appearance, and the lesion was composed of mesothelium-like cells. The histologic and immunohistochemical findings suggested that the tumor developed from mucinous metaplasia of the coelomic mesothelium.

4群リンパ節転移を伴う下行結腸sm癌の1例を経験した. 症例は55歳の男性で, スクリーニング目的の下部消化管内視鏡検査にて下行結腸に径10mmのIs型ポリープを認めたため内視鏡的摘除術を施行した. 切除標本は深達度sm1であったが, 水平断端が陽性の可能性があったため, 追加切除の適応と考え根治手術を施行した. 術中所見で1群から大動脈周囲リンパ節までの広範な転移を迅速組織診断にて確認したため, 治癒切除は不可能と考え下行結腸部分切除術 (1群リンパ節郭清) を施行した. 病理組織学的診断では内視鏡的摘除術を施行した部位に癌の遺残はなかった. 術後14病日より5FU, アイソボリンによる化学療法を開始し, 計4クール施行後の腹部CTでは, 大動脈周囲リンパ節転移が消失し著効した. 大腸sm癌の中でも本例のように深達度sm1での4群リンパ節転移陽性例は極めてまれであり, 若干の文献的考察を加えて報告する.
