Cholangiocarcinoma is a low-frequency neoplasm of onset with a poor prognosis. Peritoneal carcinomatosis is the most frequent site of metastasis with a standard palliative chemotherapy treatment. In the present article, we describe the case of a 35-year-old woman with peritoneal carcinomatosis secondary to an intrahepatic cholangiocarcinoma who was treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) as a non-standard therapeutic method. The patient has disease-free survival of 12 months with very good quality of life. The treatment of peritoneal metastasis from cholangiocarcinoma by CRS and HIPEC is feasible and could proportion better survival to these patients compared to systemic palliative chemotherapy. These therapeutic modalities can complement each other.
