FIG 1. Case 1.
A and B, Plain radiographs. Lateral plain radiograph (A) shows a large expansile mixed radiolucent/radiopaque lesion involving the right mandibular angle. Posteroanterior view of the right mandible (B) shows an anterior displacement of the first molar and a posterior displacement of the germ of the second molar. Scattered calcifications are seen.
C and D, CT scans. Axial view of the mandible (C) shows a large expansile radiolucent lesion of the mandibular angle containing scattered calcifications. Coronal view (D) shows a localized rupture of the thinned cortical plate with a posterosuperior displacement of the germ of the second molar.
E and F, Microscopic sections. These photomicrographs show the association of an ameloblastic fibroodontoma (E) with a CEOT (F) (hematoxylin-eosin, original magnification x200). The ameloblastic fibroodontoma (E) has islands of epithelial cells that exhibit an enamel organlike arrangement (arrows) seen infiltrating the connective component of the tumor, similar to the dental pulp (asterisk). The CEOT (Pindborg tumor) (F) has epithelial cells (arrows) seen with foci of amyloidosis (asterisk)
