[A patient with hepatocellular carcinoma originating from the caudate lobe, who underwent hepatectomy following microwave coagulation therapy].

Hepatocellular carcinoma (HCC) originating from the caudate lobe is rare (about 2%), and prognosis is poor due to difficulties in early diagnosis, transarterial chemoembolization (TAE), and surgical resection. Distant metastasis is also likely to develop. To prevent metastasis during surgical manipulations, we performed microwave coagulation therapy before caudate lobectomy in one patient. Although the efficacy of this procedure remains to be elucidated, the multidisciplinary treatment described in this study is essential for the improvement of prognosis in patients with HCC developing from caudate lobe.
