Giant cell tumor of uterus resembling osseous giant cell tumor: case report and review of literature.

Osteoclast-like giant cells (OLGCs) are multinucleated cells of histiocytic lineage and have been identified in a wide array of neoplasms. In the uterus, they have most frequently been reported in association with leiomyosarcomas.
