Summary
A rare ameloblastic fibro-odontoma was diagnosed in an 11-year-old girl presenting with a mandibular lesion. Microscopic analysis confirmed this mixed odontogenic tumor, originating from dental tissues.
Area of Science:
- Oral and Maxillofacial Surgery
- Pediatric Dentistry
- Oral Pathology
Background:
- Odontogenic tumors are neoplasms originating from tooth-forming tissues.
- Ameloblastic fibro-odontoma is a rare mixed odontogenic tumor with both epithelial and ectomesenchymal components.
Observation:
- An 11-year-old girl presented with a lesion on the left mandible.
- Radiographic imaging revealed a well-defined radiolucent region with an irregular radiopaque mass (3 cm).
- Initial presumptive diagnosis was complex odontoma.
Findings:
- Microscopic examination showed odontogenic epithelium, stellate reticulum-like cells, and dental papilla-like stroma.
- Presence of dentin and enamel confirmed the diagnosis.
- Final diagnosis: ameloblastic fibro-odontoma.
Implications:
- Accurate diagnosis of ameloblastic fibro-odontoma is crucial for appropriate management.
- Understanding the histopathological features aids in differentiating it from other odontogenic tumors.
- This case highlights the importance of thorough histopathological evaluation for rare oral lesions.
