A 78-year-old woman was admitted to our hospital with the chief complaint of abdominal distension. An abdominal ultrasonography and CT scan showed multiple septations in a large amount of ascites, which is a characteristic finding of pseudomyxoma peritonei. Operative findings included mucinous tumors in the right ovary and the appendix. Microscopically, well-differentiated adenocarcinomas were identified within both of these organs.
After the surgical resection of the tumors, a Tenckhoff catheter was positioned within the abdominal cavity. Through the catheter, the peritoneal lavage was performed everyday, and four cycles of intraperitoneal 5-FU administration were executed for four months following the surgery.
Serum and ascitic CEA, CA19-9, and CA125 were miraculously decreased, and no mucinous tumor was identified at the staging laparotomy after the completetion of the intraperitoneal chemotherapy.
