case_images: Microscopic examination of the specimen showed small islands and narrow cords of odontogenic epithelium, consisting of stellate cells in the center and palisading columnar cells in the periphery, located within a rich mesenchyme that contained round, stellate, or spindle-shaped cells (Figure 3), similar to those seen in the dental papilla.
