A 74-year-old woman with history of abdominal distension and pain was found in abdominal CT to have a slight fluid collection. Laboratory studies showed only high serum CA 15-3 and CA125. Laparotomy showed widespread metastasis to the parietal peritoneum and the greater omentum, but other abdominal organs were normal. Intraoperative pathological findigns diagnosed as a cancer something like ovarian cancer. We conducted omentectomy and CDDP administered intraperitoneally at surgery. Histology of resected tissues showed extra-ovarian peritoneal serous papillary carcinoma. She underwent adjuvant chemotherapy with intravenous CDDP, with no sign of a peritoneal tumor found at the second-look operation after 8 months, although a few cancer cells were still found histologically in the resected residual omentum. She underwent additional chemotherapy and has shown no recurrence after 24 months of follow-up. It is important to think EPSPC as a differential diagnosis of peritonitis carcinomatosa with indistinct primary tumor.
