Comparative cytologic and histologic studies in oral leukoplakia

Area of Science:

• Oral Medicine
• Oncology
• Pathology

Background:

• Oral leukoplakia is a potentially malignant lesion.
• Accurate diagnosis is crucial for early cancer detection.
• Cytologic and histologic methods are used for diagnosis.

Purpose of the Study:

• To compare cytologic and histologic findings in oral leukoplakia.
• To evaluate the diagnostic efficacy of cytology for malignancy.
• To correlate clinical types with diagnostic results.

Main Methods:

• Comparative analysis of 201 oral leukoplakia cases.
• Evaluation of cytologic and histologic results.
• Classification based on clinical types: erosive, verrucous, and simplex leukoplakia.

Main Results:

• Agreement between cytologic and histologic results observed in 76.6% of cases.
• Carcinoma detected in 32.9% of erosive leukoplakias and 3.2% of verrucous leukoplakias.
• Cytology demonstrated higher efficacy in detecting malignancy within the erosive leukoplakia subgroup.

Conclusions:

• Cytology is a valuable tool for oral leukoplakia diagnosis, particularly for erosive types.
• Histologic correlation is important, but cytology aids in identifying high-risk lesions.
• Further research can refine cytologic techniques for improved oral cancer screening.
