(J Korean Assoc Oral Maxillofac Surg 2012;38:166-70) Calcifying epithelial odontogenic tumor (CEOT) is a rarely reported benign tumor, accounting for 0.4-3% of all odontogenic tumors. Approximately 150 cases have been reported in the literature between 1958 and 2003. The age range of CEOT varies from 8 to 92 years with mean of 36.9 years, and the occurrence of the lesion in both genders is almost equal. It has 2 clinico-topographic variants: the intraosseous (94%) and the extraosseous (6%) type. The intraosseous type has a predilection for mandible (maxilla : mandible ratio of 1 : 2). The intraosseous CEOT commonly associated with non-erupted teeth accounts for more than half (52%) of the cases and usually appears as painless swelling that causes bony expansion. The location of diffused round-shaped calcifying material is inside the connective tissue stroma and epithelial islands. The tumors tend to be located toward the tooth crown, which usually has a unilocular radiolucent region containing variant radiopaque materials radiologically. In this paper, we report a case of CEOT occurring in the left mandibular first premolar of a 23-year-old female and present a brief review of the literature. Key word: Calcifying epithelial odontogenic tumor[paper submitted 2011. 8. 7 / revised 2011. 10. 13 / accepted 2011. 10. 15] times higher than that of the premolar region. About 52% of intraosseous CEOT usually appears in association with nonerupted or impacted teeth and as a painless swelling mass with cortical bone expansion 3 . It has biological properties similar to those of intraosseous ameloblastoma and normally occurs in the reduced enamel epithelium on the dental lamina remnants and tooth crown. As for the differences between CEOT and ameloblastoma, the epithelial cells do not look like ameloblast, and the location of diffused roundshaped calcifying material is inside the connective tissue stroma and epithelial islands 4 . The tumors tend to be located toward the crown of non-erupted teeth, which usually has a unilocular radiolucent region containing variant radiopaque materials radiologically. CEOT contains calcifying masses or homogenous non-cellular material within the tumor epithelium and stroma 5.

Maxillary ameloblastic fibroma: a case report

et al. 2011

View full text Add to dashboard Cite

Ameloblastic fibroma is a relatively rare benign odontogenic tumor in which both the epithelial and ectomesenchymal components are neoplastic. An 8-year-old Caucasian boy was referred to the dentist for evaluation of failed eruption of the maxillary left first molar. The panoramic radiograph showed a well-circumscribed unilocular radiolucency involving an unerupted maxillary left first permanent molar. The lesion was enucleated and the material was sent for histopathologic examination. Microscopically, it was composed by cords and islands of odontogenic epithelium in a myxoid cell-rich stroma that closely resemble the dental papilla with histopathological diagnosis of ameloblastic fibroma. After 24 months of follow-up no recurrence was observed and the maxillary left first molar erupted spontaneously through the buccal mucosa and was aligned with a fixed orthodontic appliance. This case emphasized the importance of careful differential diagnosis of intraosseous oral lesions and reported a rarity of the lesion and its atypical location.

“…It has been identified under different denominations, such as, ameloblastoma of unusual type with calcification, calcifying ameloblastoma, malignant odontoma, cystic complex odontoma, and has also been considered as a variant of simple ameloblastoma. [1] The eponym Pindborg tumor was first introduced to the literature in 1967, to describe this interesting and unique odontogenic tumor. The calcifying epithelial odontogenic tumor is a benign odontogenic tumor of epithelial origin that accounts for approximately 1% of all odontogenic tumors.…”

Calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a rare benign odontogenic tumor of locally aggressive behavior. It is more common in the posterior part of the mandible of adults, typically in the fourth to fifth decades. Its origin as well as its true malignant potential is not clearly known. It usually starts as a painless swelling and is often concurrent with an impacted tooth. A case of CEOT in a 55-year-old man with multiple myeloma is presented. Clinical, radiological, and pathologic findings are discussed.
