[A Case of Hepatic Sclerosing Hemangioma Diagnosed as Intrahepatic Cholangiocarcinoma and Treated with Laparoscopic Posterior Segmentectomy].

A 72‒year‒old man was referred to our hospital with a chief complaint of abdominal pain. Computed tomography(CT)revealed a tumor approximately 17 mm in diameter in segment 7(S7)of the liver. The tumor demonstrated ring enhancement and was associated with vascular invasion(Vp2). He was diagnosed with intrahepatic cholangiocarcinoma and underwent a laparoscopic posterior segmentectomy. Intraoperative findings revealed the tumor as a hard white mass on the surface of the liver. The patient was discharged on postoperative day 9. Histopathological examination revealed a highly sclerotic lesion with extensive hyalinization and fibrosis, leading to a final diagnosis of sclerosed hemangioma. It is generally difficult to distinguish sclerosed hemangiomas from malignant tumors preoperatively. We report this case along with a review of the literature.
