Osteoclastoma-like giant cell tumor of the liver

Abstract
A rare, osteoclastoma-like giant cell tumor developed in the macronodular cirrhotic liver of an 87-year-old man. Histogenetically, the tumor was considered to be of reticuloendothelial cell (Kupffer cell) origin. A brief review of the literature concerning the extraosseous giant cell tumors is included in this report.
