Age 20–40 years From 15 years 20–30 years
Location Mandible, dental area Mandible, non-dental areas Craniofacial bone, paranasal sinus
Clinical signs Slow growth Slow to very fast growth, facial deformity Slow growth in periorbital areas
Radiology Well demarcated, radiodensity varies according to the age of the lesion
Dental displacement with minor root resorption
Well defined, single or multi-celled
Variable radiodensity
Root resorption and dental displacement
Well defined, radiolucent
Obturation of the nasal and sinus cavities
Histology Variable, encapsulated Well demarcated, non-encapsulated, osteoid trabeculae Well demarcated, non-encapsulated, psammomatoid appearance
