抄録

We report a case of a patient who was operated on for an ovarian cancer and who presented with rectal metastasis 22 years later. In July, 2004, a 57-year-old woman was admitted to our hospital for investigation of positive stool for occult blood pointed out at a medical checkup. This patient had earlter undergone a total hysterectomy, bilateral adenexectomy, and partial omentectomy for an ovarian cystadenocarcinoma in 1982, and adjuvant chemotherapy had been performed. The patient's follow-up showed no abnormality until February 1991. Although the physical examination revealed no abnormality, a colonoscopy revealed elevated irregular lesions in the upper and middle rectum. Biopsies of both lesions showed group V, a well-differentiated adenocarcinoma. A low anterior resection with lymphadenectomy was performed. The resected specimen showed two polypoid lesions in the rectum, which appeared to be invaded from the serosal side. The pathological diagnosis was papillary serous cyst adeocarcinoma. The pathological findings of the specimen from the partial omentectomy performed in 1982 were consistent with those of the resected specimen. The patient was treated for recurrent ovarian cancer with paclitaxel and carboplatin, and has been well without any evidence of recurrent disease.
