Giant Cell Tumor of the Uterus: A Report and Review of the Literature.

Giant cell tumors are neoplasms that usually occur in the long bones of young adults. They can rarely present in the soft tissue and may display malignant behavior. Giant cell malignancies have previously been reported as tumors primary of the uterus but are exceptionally rare. Although uncommon, it is important to consider when a neoplasm with osteoclast-like giant cells is encountered. In this report, we describe a 70-year-old female patient with an unremarkable past history who presented with an enlarged uterus. Transvaginal ultrasound demonstrated multiple fibroids and a thickened endometrium. A biopsy diagnosis of a highgrade sarcoma was rendered and further refined in the surgical resection as malignant giant cell tumor of the uterus. In this case report, we describe the findings of this case and discuss the differential diagnosis of this entity.
