Summary
A rare calcifying epithelial odontogenic tumor (CEOT) was found in a woman's mandible. Microscopic analysis confirmed the typical CEOT elements within a dental sac, presenting an unusual case presentation.
Area of Science:
- Oral pathology
- Odontogenic neoplasms
Background:
- Calcifying epithelial odontogenic tumor (CEOT) is a rare jaw lesion, comprising ~1% of odontogenic tumors.
- CEOT typically occurs in the mandibular molar-premolar region, often associated with unerupted teeth.
Observation:
- An unusual CEOT case in a 37-year-old woman is presented.
- The lesion, located in the right mandibular molar area, appeared radiographically as a radiolucent lesion, mimicking a dentigerous cyst.
- The tumor was associated with an impacted mandibular first molar.
Findings:
- Microscopic examination revealed a dental sac containing characteristic CEOT components.
- These components included squamoid cells with eosinophilic cytoplasm, a homogeneous eosinophilic substance, and Liesegang ring calcifications.
Implications:
- This case highlights the importance of thorough microscopic examination for accurate diagnosis of odontogenic tumors.
- Understanding CEOT variations is crucial for effective clinical management and treatment planning.
- The differential diagnosis of radiolucent mandibular lesions should include CEOT, even when presenting atypically.
