<unk>  is the most common giant cell lesion of the jaws. These lesions are localised fibrous tissue tumours which contain osteoclasts and are usually several centimetres across. Frequently, a painless swelling that grows and expands rapidly is present. This growth can also erode through bone including the alveolar ridge, resulting in a soft tissue swelling that is purple in colour. Paresthesia of the lip has also been observed. Resorption of tooth roots is seen in 37% of cases compared to displacement of teeth in 50%. Two-thirds of lesions are found anterior to molars in the mandible, where teeth have deciduous predecessors.<unk> s are twice as likely to affect females and usually seen in those under 30-years. However, can be seen in a broad age range. Noonan syndrome Multiple<unk> s can be found in individuals with Noonan syndrome. Mutations in PTPN11 or RAS pathway genes are seen.
