Fibrous dysplasia (FD) is a benign skeletal disorder in which abnormally overgrowing bony lesion replaces normal bone. FD can affect one bone (monostotic form) or multiple bones (polyostotic form). The craniofacial bones are involved in about 10% of subjects with monostotic FD. However, its occurrence in the sinonasal tract is very rare. We report a case of monostotic FD developed only in the inferior turbinate in a 29-year-old woman. To the best of our knowledge, it is the second report of monostotic FD involving the inferior turbinate in the medical literature. We, therefore, report this rare case with a review of literature.
