Familial gigantiform cementoma with brittle bone disease, pathologic fractures, and osteosarcoma: A possible explanation of an ancient mystery

We describe four individuals of an African‐American family with a predominantly diaphyseal bone disease associated with familial gigantiform cementoma (FGC), a disorder typically seen in Caucasians. The mother and her children presented with deformities of the jaws, abnormalities of the long bones, and pre‐pubertal pathologic fractures. The index patient carried the diagnosis of osteosarcoma (OS). In addition, we provide a possible explanation for the jaw abnormalities of King Tutankhamen's father in the 18th dynasty in Egypt around 1350 BC. © 2004 Wiley‐Liss, Inc.
