Calcifying epithelial odontogenic tumor.

Pereira OH, de Carvalho LP, Lacerda Brasileiro Junior V, de Figueiredo CR - Case Rep Pathol (2013)

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: An incisional biopsy ensued and the specimen was sent to the Laboratory of Oral Pathology. The histopathological analysis revealed layers of odontogenic epithelial cells that formed prominent intercellular bridges. Areas of extracellular, eosinophilic, and amyloid-like material with an occasional formation of concentric calcifications (Liesegang rings) were also present (Figure 4). Based on histological findings, the final diagnosis was a calcification epithelial odontogenic tumor.
