Resumo: Objective:To analyze a case series of calcifying epithelial odontogenic tumors (CEOTs)-Pindborg tumor-.

Study Design:Twenty cases of CEOT were collected. Their histopathological, histochemical-immunohistochemical, and clinical-radiographic features were reevaluated.

Results:CEOT accounted for 0.02% of oral pathologies. Seventeen cases (85%) were intraosseous: 14 (82%) solid and three (18%) cystic CEOTs. Three cases (15%) were peripheral-extraosseous: two (67%) solid and one (33%) cystic CEOT. One case (intraosseous) was malignant. Three cases (15%) showed clear cells and two (20%) had fusiform cells. Amyloid and calcifications were observed in all cases. Mean age was 36 years (10-71 years). Prevalence was higher in women (12cases; 60%), and the most frequent location was the mandible (14cases; 70%). Clinical-radiographic diagnosis of intraosseous and peripheral-extraosseous tumors, respectively, was benign odontogenic tumor (50%) and epulis (67%).

Conclusions:CEOT is infrequent. Its morphological features vary greatly, making diagnosis challenging. Thorough analysis of the histopathological, histochemical-immunohistochemical, and clinical-radiographic features is necessary to establish diagnosis.
