Clear-cell odontogenic tumor, initially classified as benign, exhibits malignant behavior. Recurrences and distant metastases highlight its aggressive nature, challenging current classifications.

Area of Science:

Oral pathology
Oncology
Head and neck cancer

Background:

The classification of odontogenic tumors is crucial for accurate diagnosis and treatment planning.
The World Health Organization (WHO) classification system is the standard for categorizing these lesions.
Clear-cell odontogenic tumor (CCOT) has been historically debated regarding its biological behavior.

Observation:

A specific case initially diagnosed as ameloblastoma presented with characteristics requiring re-evaluation.
The observed tumor exhibited features that contradicted a benign diagnosis, prompting further investigation.

Findings:

Despite its inclusion as a benign entity in the latest WHO classification, CCOT demonstrates a propensity for aggressive behavior.
Literature review and case observations indicate repeated recurrences and the potential for distant metastases associated with CCOT.

This suggests that CCOT possesses malignant potential, irrespective of its current benign classification.

Implications:

The findings necessitate a re-evaluation of the current WHO classification of clear-cell odontogenic tumors.
Clinical management strategies for CCOT should consider its potential for malignancy, including aggressive local recurrence and distant spread.
Further research is warranted to elucidate the molecular mechanisms underlying CCOT's malignant behavior and to refine diagnostic criteria.
