Abstract

Pindborg tumor or Calcifying Epithelial Odontogenic Tumor (CEOT) derived from the enamel epithelium. It is benign, rare (less than 1% of odontogenic tumors), painless, slowly evolving, hardand is embedded in the bone. It is frequent in subjects between 20 and 60 years old, with a balanced sex ratio. The area of predilection is the mandibular bone. The objective of this study was to diagnose Pindborg tumor and to determine its management. We report the case of a 58-year-old woman, evolving for 10 years in the left ramus. The tumor was removed by enucleation under general anesthesia, then a recurrence occurred after three years. It was painless, bone-like, firm, benign looking, filling the vestibule. CT scan showed a mixed density osteolytic and osteocondensing image in the left ramus, blowing out the cortical bone, partitioned and seat of multiple calcifications. The second procedure consisted of an interrupting mandibular resection and immediate placement of a titanium screw plate for reconstruction.This tumor may be confused with ameloblastoma, ossifying fibroma, and other odontogenic tumors with mineralized components. The anatomopathological examination of the surgical specimen confirmed the diagnosis of CEOT. Because of its compartmentalized form, interrupted bone resection is the best technique to avoid recurrence.
