Ultrastructure of the keratinizing and calcifying odontogenic cyst.
Four types of cells in the keratinizing and calcifying odontogenic cyst can be identified. The "basal cell" and "stellate reticulum-type cell" contained various amounts of tonofilaments and organelles. The "ghost cell" contained coarse bundles of tonofilaments intermingled with dilated membranous organelles. The "hornified cell" contained densely packed tonofilaments. Calcification of the ghost cell and hornified cell occurred with concomitant calcification of the adjacent collagen.
