Osteoclastoma, commonly known as giant cell tumor, probably arises from zone of intense osteoclastic activity. It comprises 4-9% of all primary bone tumors and 18-23% of benign bone tumors. Peak age of involvement is during the 3rd decade. It generally occurs after closure of epiphysis, which is a main differentiating point from aneurysmal bone. OSTEOCLASTOMA (GIANT CELL TUMOUR) Giant cell tumour (GCT) is a common bone tumour with variable growth potential. Though generally classified as benign, it tends to recur after local removal. Frankly malignant variants are also known.

A number of tumors have giant cells, but are not true benign giant-cell tumors. These include, aneurysmal bone cyst, chondroblastoma, simple bone cyst, osteoid osteoma, osteoblastoma, osteosarcoma, giant-cell reparative granuloma, Giant-cell tumor of the tendon sheath and brown tumor of hyperparathyroidism Giant Cell Tumor. Giant Cell Tumors are benign, aggressive tumors typically found in the epiphysis of long bones, most commonly at the distal femur and proximal tibia. Patients typically present between ages 30 and 50 with insidious onset of pain of the involved extremity with activity, at night, or at rest Rare extraskeletal locations of osteoclastoma-like giant cell tumors have been found in thyroid, pancreas, breast, skin and heart. In our case, a 40-year-old male patient, such a tumor was found in the left upper lobe bronchus with atelectasis due to bronchial obstruction 12. Radiographic presentationAmeloblastoma is osteolytic lesionUnilocular or multilocul radiolucencyMultilocular lesion may be :Honey combed (small loculation)Soap bubble (large loculation)Crtical bone may be spread &expanded ordestroyed. Unerrupted tooth may be present(resemblingdentigerous cyst) 13 Osteoblastoma is an uncommon osteoid tissue-forming primary neoplasm of the bone. It has clinical and histologic manifestations similar to those of osteoid osteoma; therefore, some consider the two tumors to be variants of the same disease, with osteoblastoma representing a giant osteoid osteoma. However, an aggressive type of osteoblastoma has been recognized, making the relationship less clear. Although similar to osteoid osteoma, it is larger

Osteoclastoma, also called giant cell tumour of bone, bone tumour found predominantly at the end of long bones in the knee region, but also occurring in the wrist, arm, and pelvis. The large multinucleated cells (giant cells) found in these tumours resemble osteoclasts, for which the tumour is named.Usually seen in female adults between the ages of 20 and 40, this relatively rare, painful. JC:-----ABSTRACT----- P4 Osteoclastoma seen between 1965 and 1984 is presented. All patients received megavoltage therapy using Telecobalt.

All patients had quantitation of pre-treatment tumour volum Giant cell rich hepatic tumors are divided into two types of mesenchymal and epithelial. Mesenchymal tumors are uncommon. Osteoclastoma-like giant cell tumor of the liver is an extremely rare mesenchymal hepatic tumor with very poor prognosis. To the best of our knowledge, only 5 cases have been reported in the English literature so far

The most frequent tumour is osteosarcoma although other types of tumors can be seen as well, such as the osteoclastoma, above all when the skull and facial bones are affected.For the diagnosis of PD markers of reabsorption (urinary excretion of hydroxyproline) and of bone formation (alkaline phosphotase) are used Osteoclastoma: A characteristic well-defined eccentric, lytic subchondral lesion involving the epiphysis and metaphysis. The borders are well defined and usually not sclerotic. Pathologic fracture is present in 5-10% of giant cell tumours. Dynamic MRI shows a fast uptake and a slow wash out of contrast.

Osteoclastoma (Bone Giant Cell Tumor): Symptoms, Diagnosis

Osteoclastoma is constituted by mononuclear, spheroid to spindle-shaped cells intermingled with numerous, evenly distributed, osteoclast- like, multinucleated giant cells [1,2]. Osteoclastoma, additionally nomenclated as giant cell tumour of bone or myeloid sarcoma, usually arises within metaphysis and extends into epiphysis of long bones tumor [too´mor] 1. swelling or morbid enlargement; this is one of the cardinal signs of inflammation. 2. a new growth of tissue in which cell multiplication is uncontrolled and progressive. Tumors are also called neoplasms, which means that they are composed of new and actively growing tissue. Their growth is faster than that of normal tissue. The stromal cells in the biopsy si)eciniens of our patient's skin lesion were of the same type, as in osteoclastoma of bone. They are equally as specific for osteoclastoma, as the multinucleated giant cells. The abundance of vascular formations, although also a characteristic sign of osteoclastoma, raises the problem of the differential.

Osteoclastoma or giant cell tumor is a benign neoplasm of the bone but often locally aggressive in nature. It is usually seen between the third and fifth decades of life. It is sometimes seen after 50 years of age, whereas it is rarely seen after 60 years of age. This is one of the bony tumors showing higher prevalence among females Several types of benign bone tumors can, in rare cases, become malignant and spread to other parts of the body . These include giant cell tumor of bone (also called osteoclastoma) and osteoblastoma. Giant cell tumor of bone mostly occurs at the ends of the long bones of the arms and legs, often close to the knee joint ( 5 )

The cytologic findings in nine cases of giant-cell tumor (osteoclastoma) of bone diagnosed by fine needle aspiration (FNA) biopsy are described. The aspirates contained a dual population of cells, consisting of mononucleated tumor cells and multinucleated giant cells (osteoclasts) The plural of osteoclastoma is osteoclastomas.

Osteoclastoma, benign - a benign but locally aggressive tumor that arises from the bone and is composed of mononuclear cells admixed with macrophages and osteoclast-like giant cells. It usually arises from the ends of long bones or the vertebrae. Clinical presentation includes pain, edema, and decreased range of motion in the affected joint The outer portion of bone is composed of compact bone, and the inner portion, termed the medullary canal, is made up of cancellous bone.Bone marrow is located within the medullary canal and is interspersed between the trabeculae.This intricate, weblike bony structure is visible on a properly exposed radiograph of the skeletal system and is often referred to as the trabecular pattern Is a type of dentigerous teeth # Leisegang rings are found in: Ameloblastoma B.

The primary bone tumor is usually observed in adolescence age group which has been shown to be part of nearly 20% of the sarcomas known today. Giant cell tumor of bone (GCTB) can be benign as well as malignant tumor which exhibits localized dynamism and is usually associated with the end point of a long bone. Giant cell tumor (GCT) involves mononuclear stromal cells which proliferate at a high. Osteochondroma and enchondroma, if left untreated, can lead to malignancy and metastasis. Chondrosarcoma very rarely metastasizes, while Ewing's sarcoma and osteosarcoma can metastasize most commonly to the lungs and liver. Ewing's may also metastasize to the abdomen. One-third of cases of osteoclastoma are malignant, but they rarely.
