Monostotic Fibrous Dysplasia of Inferior Turbinate / 대한이비인후과학회지

ABSTRACT

Fibrous dysplasia is a benign fibro-osseous lesion originally described by Lichtenstein in 1938. Currently, three general subtypes of disease are recognized monostotic, polyostotic, and McCune-Albright syndrome. Fibrous dysplasia is not rare, with the incidence report being about 5% to 7%. Common sites of fibrous dysplasia are the skeletal system including long bones, ribs, craniofacial bones, and the pelvis. However, fibrous dysplasia is rare in the nasal cavity, especially involving the turbinate. In the review of literature over the past 50 years, we were able to discover only 4 cases in which the fibrous dysplasia involved inferior turbinate, with all of them being the polyostotic form found around the sinuses. There were only 4 cases in which monostotic fibrous dysplasia involved the middle turbinate, but none the inferior turbinate. We present this case, with a review of the relevant literature, as the first report on monostotic fibrous dysplasia of the inferior turbinate.
