Familial gigantiform cementoma is an exceedingly rare but distinct subtype of cemento-osseous-fibrous lesion. Undocumented radiographic changes and related bone metabolism disorder are herein hypothesized and discussed. We present an adolescent case with recurrent familial gigantiform cementoma who received surgical intervention in our hospital. Apart from typical multiquadrant and expansile ab...

Malignant transformation in fibrous dysplasia (FD) is a rare event, reported to occur in approximately less than 1% of cases. The most common type of secondary malignant tumor arising from FD is osteosarcoma. We report a case of secondary chondrosarcoma arising in a patient with polyostotic FD. Magnetic resonance imaging (MRI) showed a multilobulated tumor, 12.6 cm in diameter, in the right sca...

Fibrous dysplasia of the temporal bone is more commonly manifested in the external auditory canal (80%) and the inner and medium ear...

Two types, monostotic or polyostotic lesions, cause progressively expanding lamp, producing cosmetic deformities functional impairments. Frequently occurs in posterior region mand...
