Simple ameloblastoma with ghost cell and granular cell components.

A rare case of simple ameloblastoma, acanthomatous type, which contained ghost cells and granular cells is reported. Although the ghost cells were noted only in the center of some tumor cell follicles, these staining properties were the same as those in the calcifying odontogenic cyst. It is suggested that, like the granular cell and hyaline body in odontogenic tumors and cysts, the presence of ghost cells is not a specific feature of the calcifying odontogenic cyst.
