Background: Multicystic peritoneal mesothelioma is a rare disease. It is not certain if it is a benign or a borderline tumor. Although many therapeutic approaches have been used, complete cytoreductive surgery in combination with hyperthermic intraoperative intraperitoneal chemotherapy has gained acceptance.
Case report: A case of multicystic peritoneal mesothelioma in a 16-year old patient is reported. The patient underwent complete cytoreduction and received intraoperative hyperthermic intraperitoneal chemotherapy. The patient is disease-free one year after surgery.
Conclusions: Complete cytoreductive surgery in combination with hyperthermic intraoperative intraperitoneal chemotherapy appears to be a rational therapeutic approach in multicystic peritoneal mesothelioma.
