1. Ameloblastic fibroma2. Odontoma3. Squamous odontogenic tumor Squamous Odontogenic Tumor: Lucent defect extending along the roots of the lateral incisor and first premolar teeth. Squamous Odontogenic Tumor. A, Low-power photomicrograph showing islands of bland-appearing squamous epithelium in a fibrous stroma. B, Higher-power photomicrograph showing bland appearance of the epithelium with microcyst formation. Ameloblastic Fibroma: Relative distribution of ameloblastic fibroma in the jaws. A multilocular radiolucent defect associated with an unerupted second molar. A, Long, narrow cords of odontogenic epithelium supported by richly cellular, primitive connective tissue. B, Basophilic epithelial islands with peripheral nuclear palisading. Ameloblastic Fibro-Odontoma: Relative distribution of ameloblastic fibro-odontoma in the jaws1. Radiolucent defect in the ramus containing small calcifications having the radiodensity of tooth structure. 2. Unilocular radiolucent defect displacing the developing mandibular third molar posteriorly. Flecks of mineralized material are present in the radiolucent defect. A, The soft tissue component of the tumor is indistinguishable from an ameloblastic fibroma. B, Formation of disorganized tooth structure can be seen. Ameloblastic Fibrosarcoma. A, A 21-year-old woman complained of facial asymmetry and recent increase in size of a mandibular mass that had been present for some years. B, Radiograph of the same patient. Note the lytic destruction of the posterior mandible. The cellular mesenchymal tissue shows hyperchromatism and atypical cells. A small island of ameloblastic epithelium is present. Compound Odontoma. 1. A small cluster of toothlike structures is preventing the eruption of the maxillary canine. 2. Compound Odontoma. Multiple toothlets preventing the eruption of the mandibular cuspid. Complex Odontoma. 1. A large radiopaque mass is overlying the crown of the mandibular right second molar, which has been displaced to the inferior border of the mandible. 2. Surgical specimen consisting of more than 20 malformed toothlike structures. 3. This decalcified section shows a disorganized mass of dentin intermixed with small pools of enamel matrix.
