title: Anaplastic giant cell tumor with mucinous cystadenocarcinoma of the ovary. Origin of the giant cells.
abstract: The present case is that of a 27 years old woman who had received right oophorectomy for ovarian cancer nine years previously. The histological diagnosis at that time was mucinous cystadenocarcinoma with anaplastic areas. The patient expired ten years after oophorectomy due to widespread metastases of the tumor. Review of the histological slides revealed ovarian giant cell tumor which was considered to be of epithelial origin differing from those appearing in giant cell tumor of bone.
