A Case Report of Hepatic Teratoma

Abstract

True hepatic teratoma is very rare. We have experienced a case of hepatic teratoma in a 14-month-old girl. This tumor was successfully removed with normal liver tissue surrounding the tumor by right hepatolobectomy. Microscopic examination showed a mature teratoma containing tissue representative of all three germ layers, which were intestine, bronchus, bone, cartilage. striped muscle, brain, and squamous epithelium. She did well postoperatively. A review of the literature on hepatic teratomas was also presented. There were 18 cases reported in the last twenty years, including 4 in adults and 14 in children. Only two out of 18 cases were malignant, and the remaining 16 cases were thought to be benign. Removal of the tumor was carried out successfully in 13 patients, and all of them are alive and well. At the persent time, surgical resection of hepatic teratoma has been most effective.
