A Case of Fibrous Dysplasia Confined Bilateral Middle Turbinates / 대한이비인후과학회지

ABSTRACT

Fibrous dysplasia, a rare bony disease, is characterized by substitution of normal bone with immature tissue embedded in a fibrous stroma. The localization of fibrous dysplasia only at the middle turbinate is an extremely rare event. The causes of fibrous dysplasia are still unknown. Recently, attention has been focused on a defect in the adenylate cyclase signal transduction system found in the pathological tissues. Nasal endoscopy shows turbinate enlargement that can be mistaken for a concha bullosa. We report a case of fibrous dysplasia confined in the bilateral middle turbinates.
