Osteoclastoma. Micrograph of a giant-cell tumor of bone showing the characteristic giant cells, H&E stain. Specialty. Oncology. Giant-cell tumor of the bone ( GCTOB ), is a relatively uncommon tumor of the bone. It is characterized by the presence of multinucleated giant cells ( osteoclast -like cells) DEFINITION • Distinct neoplasm arising from non-bone forming supportive connective tissue of marrow with network of stromal cells regularly interspersed with giant cells • Tumor is called GCT because Giant cells are found • These Giant cells resemble osteoclasts..hence called as OSTEOCLASTOMA
Giant cell tumor of bone, also called an osteoclastoma or a myeloid sarcoma, is a relatively uncommon neoplasm characterized by multinucleated giant cells. It primarily affects young adults, age 20 to 30. They usually arise in the long bones of the arms and legs, but can more rarely occur in the sacrum and vertebral body إنجليزي عربي osteoclastoma ترجمة, القاموس يمدك بالترجمة وملاحظات عليها كذلك تعبيرات اصطلاحية معاني ومرادفات جمل أمثلة مع خاصية النطق , أسئلة وأجوبة .

OSTEOCLASTOMA. Tumore del tessuto osseo, detto anche tumore gigantocellulare dell' osso, costituito da un tessuto nel quale si osserva un gran numero di cellule giganti simili agli osteoclasti. Giant cell tumor (GCT) of bone was described by Cooper and Travers ( 1) in 1818. The tumor is generally benign and characterized histologically by multinucleated giant cells with a background of mononuclear stromal cells. The multinucleated giant cells appear similar to osteoclasts, which led to the older term osteoclastoma ( 2 )
Osteoblastoma is a benign (noncancerous) bone tumor. It is a rare tumor that often develops in the bones of the spine, as well as the legs, hands, and feet. Because osteoblastomas can grow to a large size, treatment always involves surgery On palpation, it feels firm or rather soft. Osteosarcoma and osteoclastoma cause asymmetrical swelling, while Ewing's sarcoma causes symmetrical fusiform swelling of the bone. Ewing's sarcoma's surface is smooth with indistinct ends and with firm and rubbery consistency. Osteoclastoma has a smooth surface, and the consistency is bony hard. Osteoclastoma. f.

It may cause pain and restricts movement Definition. A rare bone sarcoma characterized by a usually benign space-occupying lesion, which is nevertheless locally aggressive and massively damaging to surrounding bone tissue.

This is a tumor of adulthood more commonly seen between 20 and 50 years of age, after growth plate closure.
