Central giant cell lesion (Reparative giant cell granuloma)
Central giant cell lesion is charactersied by a benign, but locally aggressive, osteolytic proliferation with reactive bone formation. The mandible is more commonly involved. This is seen in young adults and is more common in women. Clinically, the lesion is asymptomatic and may appear as a swelling sometimes causing pain and paraesthesia, especially in aggressive lesions. Radiographically it appears as a radiolucent, often multi-loculated lesion. Surgical enucleation is the treatment of choice.
