Summary: The calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a rare lesion that represents 1% of odontogenic tumors, although their histogenesis is unknown, the cells that constitute it are derivative of the intermediate layer body enamel. This type of tumor has been found in patients ranging in age from 30 to 50 years of age without gender predilection, and usually located in posterior mandible, sometimes associated with impacted third molars. Among its most common features present slow, progressive and asymptomatic growth, these lesions usually are discovered by the mandibular asymmetry that can potentially cause. Radiographically the tumor appears as a radiolucency with scalloped margins unilocular or multilocular nature, which may contain defects calcified structures with variable size and density, and sometimes containing radiopaque focus, where the treatment of choice is local resection, which results with good prognosis.

While CEOT is an uncommon condition, the objective of this study was to determine the typical characteristics such as age, location and radiographic appearance of this various odontogenic tumors, since it is extremely valuable to establish differential diagnoses and thereby achieve a plan of successful treatment, and improve the quality of life of patients.

Case summary: Male patient aged 45, who presented increased volume in right side of the face, five years of evolution, asymptomatic, slow-growing and progressive as he consults where Incisional biopsy was performed in March 2010, being operated under general anesthesia performing tumor resection and immediate reconstruction with osteosynthesis 2.7 system.
