| calcifying and keratinizing odontogenic cyst | A mixed radiolucent-radiopaque lesion of the jaws with features of both a cyst and a solid neoplasm; characterised microscopically by an epithelial lining showing a palisaded layer of columnar basal cells, presence of ghost cell keratinization, dentinoid, and calcification. Synonym: calcifying and keratinizing odontogenic cyst, Gorlin cyst. (05 Mar 2000) |

| Malherbe's calcifying epithelioma | A tumour composed of cells resembling those of the hair matrix, which undergo 'mummification' and may calcify. It is a relatively uncommon tumour, which may occur at any age from infancy. The majority of patients are under 20, and females are affected more than males. The lesion is usually a solitary deep dermal or subcutaneous tumour 3-30 mm in diameter, situated in the head, neck, or upper extremity. (12 Dec 1998) |
