Surgical management of a large calcifying epithelial odontogenic tumor in the maxilla: A case report

INTRODUCTION: The calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a locally invasive benign neoplasm. Histogenesis is controversial. PRESENTATION OF CASE: A 26-year-old male presented asymptomatic swelling on the right side of the face, with approximately six months of evolution. At intraoral examination, a hard nodule localized in the right posterior region of the maxilla, measuring approximately 5.0 x 3.0 cm was observed. The computed tomography images showed hypodense lesion with points of calcification associated with two non-erupted teeth. We suspect of odontogenic lesions. The final diagnosis of CEOT was established based on the histopathological aspects. DISCUSSION: This tumor is more frequent in adult men, usually develops in the posterior region of the mandible and may present clinical-pathological similarities with others odontogenic lesions. The radiological aspects observed in the CEOT are variable and depend on the time of evolution of the tumor. The histopathological examination is mandatory to establish the final diagnosis. CONCLUSION: Our case was treated with simple enucleation without signs of recurrence in five years of follow-up. Further studies are needed to understand the aetiology and the biological behaviour of this tumor.
