Bottom Line: Here is reported the case of a 21-year-old female patient with a CEOT in the left mandibular posterior region.A large quantity of extracellular, eosinophilic, and amyloid-like material and an occasional formation of concentric calcifications (Liesegang rings) were also found.Resection of the tumor with a safety margin was performed and after 6 months of follow-up there has been no sign of recurrence of the lesion.

ABSTRACT
The calcifying epithelial odontogenic tumor (CEOT) is a rare benign epithelial odontogenic neoplasm of slow growth that is locally aggressive and tends to invade bone and adjacent soft tissue. Here is reported the case of a 21-year-old female patient with a CEOT in the left mandibular posterior region. The computerized tomography in coronal plane revealed a hypodense lesion in the posterior region of the left mandibular body with hyperdense areas inside and was associated with element 37. An incisional biopsy of the lesion was performed and the histopathological analysis revealed the presence of layers of epithelial odontogenic cells that formed prominent intercellular bridges. A large quantity of extracellular, eosinophilic, and amyloid-like material and an occasional formation of concentric calcifications (Liesegang rings) were also found. The histopathological diagnosis was a Pindborg tumor. Resection of the tumor with a safety margin was performed and after 6 months of follow-up there has been no sign of recurrence of the lesion.

Mentions: The patient reported a clinical evolution of only five months of the lesion. A radiographic exam revealed a diffuse radiolucent, unilocular lesion, associated with region 37, yet including the distal root of region 36 up to the crown of region 38 (Figure 2). Using a computerized tomography in coronal section, it was possible to observe that it was a question of a local hypodense lesion in the mandibular region, containing irregular hyperdense areas in its midst, compatible with the presence of mineralized tissue in the lesion. Further, it was also noted that the tumor caused expansion of the vestibular cortical bone and showed resorption of the cortical bone of the alveolar process (Figure 3). Based on clinical and radiographic findings, diagnostic hypotheses suggested a dentigerous cyst, unicystic ameloblastoma, and CEOT.
