Central giant-cell granuloma (CGCG) is a localised benign condition of the jaws.It is twice as common in females and is more likely to occur before age 30. Central giant-cell granulomas are more common in the anterior mandible, often crossing the midline and causing painless swellings.
Malignancy in giant-cell tumor is uncommon and occurs in about 2% of all cases. However, if malignant degeneration does occur, it is likely to metastasize to the lungs. Giant-cell tumors are normally benign, [1] with unpredictable behavior. [2] It is a heterogeneous tumor composed of three different cell populations.
Patients typically present with swelling with or without pain. The slow-growing tumor predominantly arises in long bones in a subcortical location (95% in the tibia or fibula). [3] Benign osteofibrous dysplasia may be a precursor of adamantinoma [4] [7] or a regressive phase of adamantinoma. [8]
Tenosynovial giant cell tumor (TGCT) is a non-malignant tumor defined histologically as inclusions of “osteoclast-like” multinucleated giant cells, hemosiderin, and macrophages. [1] This histology can present one of 2 clinically distinct ways. TGCT tumors often develop from the lining of joints (also known as synovial tissue).
A giant cell (also known as a multinucleated giant cell, or multinucleate giant cell) is a mass formed by the union of several distinct cells (usually histiocytes), often forming a granuloma. [ 1 ] Although there is typically a focus on the pathological aspects of multinucleate giant cells (MGCs), they also play many important physiological roles.
The tumor also affects the growth of the jaw. In early adolescent years the tumor can go undetected because the tumor cannot cause complications until it has grown at a large size. The tumor affects the jaw, which is more commonly found in the mandible and there has been hardly any cases with the maxillary but it can still happen. [6]
A non-ossifying fibroma (NOF) is a benign bone tumor of the osteoclastic, giant cell-rich tumor type. [1] It generally occurs in the metaphysis of long bones in children and adolescents. [ 2 ] Typically, there are no symptoms unless there is a fracture . [ 2 ]
