title: [A case of multiple hepatic epithelioid hemangioendothelioma mimicking metastatic hepatic tumor].
abstract: We report a case of multiple hepatic epithelioid hemangioendothelioma( EHE) mimicking hepatic metastasis of colon cancer. A 71-year-old man was referred to our hospital for further evaluation of multiple hepatic tumors. Enhanced CT scan was not performed because of renal dysfunction. Total colonoscopy revealed a type 1 cancer at the rectosigmoid junction. We therefore diagnosed the hepatic tumors as metastases from rectal cancer. Anterior resection was performed and postoperative chemotherapy targeting the hepatic tumors was carried out. Unfortunately, the size of the hepatic tumors increased. We therefore performed lateral segmentectomy and partial hepatectomies (11 lesions). The macroscopic findings indicated basically localized tumor without diffuse infiltration. Microscopically, spindle and oval-shaped cells with abundant eosinophilic cytoplasm were observed; immunohistochemical staining was positive for factor VIII and CD34. These data were conclusive for EHE. EHE of the liver is a rare neoplasm of which little is currently known. We herein report a case of EHE in the liver, misdiagnosed as colorectal metastatic tumor.
