An associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)has been developed as a novel surgical technique for patients with insufficient future liver remnant volume even after portal vein embolization(PVE)±hepatic arterial or venous embolization or conventional two-stage hepatectomy(TSH)(1-5).ALPPS was thought to be a breakthrough but high-risk procedure;however,it recently became a safer technique after the developing phase(1-3).Conversion surgery is strongly recommended for patients with initially unresectable liver tumors that are deemed resectable by systemic chemotherapy or hepatic arterial chemotherapy/embolization(6,7).The primarily targeted diseases are colorectal liver metastases(CRLM)and hepatocellular carcinoma(HCC).ALPPS is indicated for patients undergoing not only primary surgery but also conversion surgery.

Curability and safety are essential for patients with advanced liver malignancy undergoing extended liver *** the future liver remnant(FLR)volume is insufficient,portal embolization with or without hepatic arterial or venous embolization or a conventional two-stage hepatectomy(TSH)can be performed(1,2).Associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)was introduced in 2007.

BACKGROUND An ectopic hepatocellular carcinoma(EHCC)arises from the ectopic liver which is defined as a hepatic organ or tissue not connected to surrounding *** is a rare disease and it is difficult to diagnose ***,the clinical features are not fully *** SUMMARY A retroperitoneal tumor(6 cm)was located at the dorsal side of the pancreas head on abdominal ultrasonography in an 81-year old woman positive for hepatitis C virus *** enhanced-computed tomography and gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging showed viable HCC patterns with early enhancement and delayed *** tumor markers-serum alphafetoprotein and alpha-fetoprotein-L3%-were increased to 30.1 ng/m L and83.1%,*** induced by vitamin K absence or antagonist-Ⅱwas within normal levels(17 m AU/m L).Positron emission tomography-computed tomography showed strong accumulation into the tumor(Standardized Uptake Value max:13.8),and the tumor cytology following endoscopic ultrasoundguided fine needle aspiration showed poorly differentiated *** extirpation was performed,and operative findings showed that the retroperitoneal tumor was disconnected from the pancreas and the *** lymph nodes near the tumor were histologically *** histological examination,the tumor was finally diagnosed as EHCC with Arginase-1 positive *** We report our experience of a rare EHCC which was difficult to diagnose,and we present a review of the literature.
