Summary:A 42-year-old man who had undergone appendectomy 30 years ago was referred to our hospital for treatment of pseudomyxoma peritonei (PMP). Because of an episode of mucosuria, he visited the department of urology of another hospital. Radiologic images showed a massive multicystic tumor in the abdominal cavity. Laparotomy and partial resection of the tumor were performed, and histopathological findings showed a low-grade mucinous carcinoma associated with PMP. After being admitted to our hospital, magnetic resonance imaging was performed, and it revealed fistula formation between the cystic tumor below the navel and the urinary bladder. We diagnosed PMP arising from the urachus, and partial resection of the urinary bladder, greater omentectomy, right hemicolectomy, splenectomy, cholecystectomy, and radical peritonectomy were performed. After complete cytoreduction, hyperthermic intraperitoneal chemotherapy was administered. Since PMP arising from the urachus is extremely rare, we have reported this case with a review of the literature.
