Hematoxylin and eosin staining for the gingival lesion. (a) The black arrow indicates a dental papilla-like tissue. (b) The red arrows denote abundant small blood vessels. (c) A large mineralized matrix appears like enamel or dentin structures. (d) There are several islands of odontogenic epithelium. One of them clearly exhibits enamel organ differentiation. Panels (b), (c), and (d) are magnifications (×4) of the white squares of panel (a). Scale bar = 200 μm for panel (a) and 50 μm for panels (b), (c), and (d).
