A 74-year-old man presented with mucosal sweeling measuring 8 mm in the area of lower right canine. X-ray examination showed in that location a sharply demarcated unicystic radiolucency in mandible.
The lesion was enucleated and the microscopical examination showed the lesion to be a calcifying cystic odontogenic tumor. The diagnosis and differential diagnosis of odontogenic tumors containing ghost cells is discussed.
