Giant cell tumor of bone is a rare, fast-growing non-cancer tumor. It most often grows in adults between ages 20 and 40 when skeletal bone growth is done. It is slightly more common in women. It usually grows near a joint at the end of the bone. The location of a giant cell tumor is often in the knee, but can also grow in the bones of the arms. Giant cell tumor (GCT) of the soft tissue (GCT-ST) is a rare, unusual primary soft tissue tumor that is completely distinct from, and should not be confused with, any giant cell-rich tumor of bone or soft tissue. Currently, GCT-ST is included in the group of so-called fibrohistiocytic tumors of intermediate (borderline) malignancy Results: We identified 4 large series of patients with malignant giant cell tumor of bone that provided data on 2315 patients with giant cell tumor of bone. Across these studies, the cumulative incidence of malignancy was 4.0%; the cumulative incidence of primary malignancy was 1.6% compared with 2.4% for secondary malignancy Giant cell tumors (GCT) of bone is benign bone tumors with aggressive and osteolytic activity.

Giant cell tumor of bone (GCTB) consists of three distinct cellular constituents. (1) Circular shaped mononuclear cells, (2) Spindle-like stromal cells, and (3) Osteoclast-like multinucleated giant cells [].Stromal cells contribute to the involvement of tumor-related myeloid lineage cells and also help in the establishment of osteoclast-like giant cells which lead to the bone desorption processes Giant cell tumors (GCTs) are a rare etiology of head and neck tumors. These benign neoplasms mainly affect the long bones. A trend toward local recurrence and late malignant change with distant metastases, especially to the lung, has been reported (1, 2).Complete surgical resection is the gold standard treatment but may lead to significant functional deficits in this particular localization Giant cell tumors (GCTs) of the tendon sheath are the second most common tumors of the hand, with simple ganglion cysts being the most common. [] Chassaignac first described these benign soft-tissue masses in 1852, and he overstated their biologic potential in referring to them as cancers of the tendon sheath Subependymal giant cell astrocytomas (SGCAs or alternatively SEGAs) are benign tumors (WHO grade I), seen almost exclusively in young patients with tuberous sclerosis. They can be either asymptomatic or symptomatic due obstructive hydrocephalus, surgery treatment is often curative. On imaging, they classically appear as an intraventricular mass.
