X-ray of a giant-cell bone tumor in the head of the fourth metacarpal of the left hand. On X-ray, giant-cell tumors (GCTs) are lytic/lucent lesions that have an epiphyseal location and grow to the articular surface of the involved bone. [8] Radiologically the tumors may show characteristic 'soap bubble' appearance. [9]
In mixed tumors, giant cells are more likely to be found in higher proportions at the edge of a tumor. [11] When extensive necrosis is present, it is possible for a giant-cell tumor to have only a thin rim of viable cells remaining at the perimeter of the mass. [citation needed]
Subependymal giant cell astrocytoma (SEGA, SGCA, or SGCT) is a low-grade astrocytic brain tumor (astrocytoma) that arises within the ventricles of the brain. [1] It is most commonly associated with tuberous sclerosis complex (TSC). Although it is a low-grade tumor, its location can potentially obstruct the ventricles and lead to hydrocephalus.
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.
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.
Giant-cell tumor (GCT) of the pelvis is uncommon, accounting for only 1.5 to 6% of cases of GCT. [1] In pelvis ilium is the most common site of involvement; ischium and pubis are less frequently involved. [2] It typically presents in adults between age of 20 to 50 with localized swelling and pain. [3] Females are slightly more affected than ...
Chondroblastoma was first described in 1927 as a cartilage-containing giant cell tumor by Kolodny but later characterized by Codman in 1931. [ 1 ] [ 4 ] Codman believed chondroblastoma to be an "epiphyseal chondromatous giant cell tumor" in the proximal humerus .
