Is GCT radiopaque?
A grade 1 lesion (latent) has a well-defined margin and an intact cortex. A grade 2 lesion (active) has a relatively well-defined margin but no radiopaque rim, and the cortex is thinned and moderately expanded.
Is GCT a sarcoma?
Giant cell tumor (GCT) of bone is a generally benign, but often locally aggressive, neoplasm of bone, with a propensity for recurrence. Sarcomatous transformation is rare and typically occurs with a history of recurrences and radiation treatment.
Which is the most common site of Osteoclastoma?
The most common bones involved are the long bones; less common are the jaws, vertebrae, scapula pelvis and small bones of hands and feet. Osteoclastoma is not commonly found in its early stage.
How common is giant cell tumor?
Giant cell tumors usually occur in young adults, and are slightly more common in females. They are quite rare, occurring in only about one out of every one million people per year. Although giant cell tumors are not cancerous, they are aggressive and can destroy the surrounding bone.
Is GCT malignant?
Malignant giant cell tumor (GCT) of bone is a rare tumor with debilitating consequences. Patients with GCT of bone typically present with mechanical difficulty and pain as a result of bone destruction and are at an increased risk for fracture.
Is Osteoclastoma malignant?

Whats is GCT?
The glucose challenge test, also called the one-hour glucose tolerance test, measures your body’s response to sugar (glucose). The glucose challenge test is done during pregnancy to screen for gestational diabetes — diabetes that develops during pregnancy.
Which tumor shows osteoclastic giant cells?
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).
