“…Cystic transformation of the follicle associated with the unerupted tooth may also occur when the eruption pathway is impeded by the odontoma. 19,22 This etiology could explain the simultaneous occurrence of dentigerous cyst and odontoma in this case report. Concurrent formation of odontogenic tumors and cyst formation have been rarely reported in veterinary literature.…”

“…Several studies document simultaneous cyst and odontoma, and there is one case report of a dentigerous cyst and complex odontoma published in 2009. 19,21,22 In one human study of 351 odontomas, dentigerous cysts were diagnosed in conjunction with 27.6% of the odontomas. 21 In a second human study of 81 odontomas, dentigerous cyst was associated with 9% of odontomas.…”

A 7-month-old, male, Weimaraner dog was presented for maxillary swelling. Clinical evaluation including radiographs and computed tomography revealed a large cystic lesion, unerupted right maxillary canine tooth, and mass presumed to be a compound odontoma. The cyst and mass were expansile and occupied a large portion of the nasal cavity displacing anatomical structures of the maxilla. The mass was excised via curettage through an intraoral surgical approach and the unerupted tooth and cystic lining were removed. Histopathology supported dentigerous cyst and compound odontoma. This case confirms the first report of concurrent development of dentigerous cyst and compound odontoma in a dog with successful treatment and 18-month follow-up with no recurrence.

Background: Odontogenic cysts have the potential to transform into neoplasms. However, the characteristics of those which transformed to neoplastic tissues have not been well described and the exact causes of that phenomenon are not yet clear. Objectives: This study aims to describe characteristics of odontogenic cysts that transformed into neoplasms and to look for their potential etiologies. Data Sources: English-written studies indexed in PubMed, Science Direct, and Proquest were assessed using keywords verified by Medical Subject Headings: ‘Odontogenic Cyst’ and ‘Neoplastic Cell Transformation’. Study Eligibility Criteria: Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines were used as guidance. Participants: Following steps in PRISMA guidelines, 19 articles were fully reviewed (three case series and 16 case reports) with 27 subjects of 16 males (59%) and 11 females (41%) from 15 to 86 years old. Results: Cystic origins were eight dentigerous cysts, four odontogenic keratocysts, two residual cysts, one radicular cyst, one calcifying odontogenic cyst, one follicular cyst, one glandular odontogenic cyst, and nine unspecified odontogenic cysts that transformed to ameloblastoma (3 cases) and carcinoma (24 cases). Limitations: Neoplastic transformations of odontogenic cysts arose from epithelial remnants of inadequate odontogenic cyst removal and chronic inflammation due to infection. However, the exact causes of their transformations remain unclear. Conclusions: Therefore, careful removal of odontogenic cysts and regular postoperative follow-ups are key to prevent recurrence and neoplastic transformation. Future studies are needed to investigate potential causes of neoplastic transformation of odontogenic cysts.

“…Ameloblastic fibroma is a true mixed odontogenic tumor and comprise of both epithelial and mesenchymal constituents occurring mostly in young patients in first or second decades of life. [ 2 13 ] The lesion is mostly seen in the posterior region of mandible. [ 3 ] Ameloblastic fibromas are more common in males than females.…”

Ameloblastic fibroma is a rare mixed odontogenic benign tumor that can occur in either mandible or maxilla but mostly it is found in posterior region of mandible. It can present either peripherally or centrally with a majority of the cases predominantly occurring in first two decades of life and mostly affects male patients. It is characterized by epithelial islands and cords submerged in ectomesenchyme that bear resemblance to the dental papilla and enamel organ but without actual hard tissue formation. Ameloblastic fibroma is a rare odontogenic tumor consisting of neoplastic epithelial and mesenchymal tissues. Recent reports have suggested that this lesion has the potential for high recurrence (18%) and greater chances of recurrent Ameloblastic fibroma transforming into Ameloblastic fibrosarcoma (45%). A 34-year-old male patient presented with pain and swelling in right mandibular posterior region. Intraorally expansion of buccal cortical plate with tenderness over swelling was present. Extraoral examination revealed facial asymmetry on right side. In view of imaging and clinical findings, provisional diagnosis of Odontogenic Keratocyst or Recurrent Ameloblastoma was considered. After obtaining informed consent and general systemic evaluation, the lesion was enucleated under general anesthesia and biopsied which confirmed the diagnosis of Ameloblastic fibroma. Ameloblastic fibroma is a mixed odontogenic tumor composed of odontogenic ectomesenchyme resembling dental papilla with epithelial strands and nests similar to the dental lamina and enamel organ, but with no dental hard tissue formation. Odontogenic tumors, Ameloblasts, Ameloblastoma, Jaw neoplasm.
