PDF: Florid Osseous Dysplasia: Report of Two Cases and a Review of the Literature

Florid osseous dysplasia (FOD) is an osseous dysplasia rarely presenting in the jaws.

Florid-Osseous-Dysplasia



It belongs to the spectrum of fibro-osseous lesions and represents a reactive process in which normal bone is replaced by poorly cellularized cementum-like materials and cellular fibrous connective tissues (Lin et al., 2010).

The latest World Health Organization’s classification (WHO) in 2005 of benign tumors recognized FOD as lesions associated with bone and designated them as florid osseous dysplasia that forms along with focal osseous dysplasia, periapical osseous dysplasia and familial gigantiform cementoma, the group of osseous dysplasia (Barnes et al., 2005).

FOD is commonly seen in black women of middle age (40-50 years-old). It often occurs bilaterally in the mandible with symmetric involvements (Lin et al.), but it can also affect the maxilla.

The process may be totally asymptomatic and in such cases, the lesion is detected when radiographs are taken for some other purposes.
