Giant cell tumor (“osteoclastoma”) of the pancreas: A tumor of epithelial origin

Abstract

Carcinomas of the pancreas with giant cells are not rare, but those containing osteoclast‐like tumor cells are quite unusual. This report documents a pancreatic neoplasm comprising both easily recognizable well‐differentiated adenocarcinoma and osteoclast‐like tumor. The literature on the “osteoclastoma” of the pancreas is reviewed. Evidence for its epithelial deviation is supported strongly by the present case. Copyright © 1981 American Cancer Society
