Cementomas--aggressive or innocuous neoplasms?

No class of tumor is so inadequately discussed in the otolaryngology literature as the "cementomas". Until recent years, four distinctly different benign fibro-osseouslesions containing cementum were clumped together under the heading of cementoma. The separate entities in this tumor class are benign cementoblastoma (true cementoma), cementifying fibroma, peripical cemental dysplasia, and gigantiform cementoma (florid osseous dysplasia). Only an occasional case of the gigantiform variant or an unusually aggressive cementifying fibroma requires an extensive operation for complete excision.
