Very few cases of gigantiform cementoma have been reported, and those associated with a positive family history are especially rare. Confusion exists about the relationship of gigantiform cementoma to florid osseous dysplasia, cementifying fibroma, and diffuse chronic sclerosing osteomyelitis. It has been unclear whether gigantiform cementoma should be accorded the status of a separate entity. In this article, we report our findings on a family that, over five generations, has exhibited clinical, radiographic, and/or histologic findings consistent with the designation familial gigantiform cementoma. This pedigree consists of 55 members. Significant heterogeneity in expression of this trait was noted. The pattern of occurrence of the trait is consistent with an autosomal dominant mode of inheritance with variable expressivity of the phenotype. We suggest that familial gigantiform cementoma should be recognized as a separate entity.
