측두골에 발생한 섬유성 이형성증 1례

Fibrous dysplasia is a relatively rare condition characterized by benign idiopathic disorder where abnormal fibrous-osseous tissue and irregular bony trabecule replace normal cancellous bone.

It can be associated with endocrine disorder, growth disturbance, sexual maturation and abnormal pigmentation of the skin and mucous membrane.

If it is found in the craniofacial area, the maxilla or mandible is usually involved, but extremely rare in temporal bone. The authors experienced a case of monostotic fibrous dysplasia of temporal bone in 14 year-old male, and report this case with brief review of literatures.
