MATERIALS & METHODS OMF cases (2000–2011) from the patients containing records of age, sex, and histological diagnoses were retrieved from the Oral Pathology Department of our institution. Our cohort was categorized as 0–99 years, 0–15 years, and >60 years respectively for the general, pediatric and geriatric patients. These lesions were classified into four main categories: tumor/tumor-like reactive lesions, cystic/pseudocystic lesions, inflammatory/infective lesions, and others/miscellaneous lesions. RESULTS 1.A total of 37,210 OMF diagnoses (20992 patients, 23061 lesions) were included in the category of general patients. Most of these lesions were distributed in the group of tumor/tumor-like reactive lesions, followed by the groups of inflammatory/infective lesions, cystic/pseudocystic lesions, and others/miscellaneous lesions. Squamous cell carcinoma was the most common OMF lesion, and was also the most frequent malignant lesion. 2.A number of 848 OMF diagnoses (780 patients, 819 lesions) were recorded in the pediatric patients. Most lesions were in the inflammatory/infective group, followed by the groups of tumor/tumor-like lesions, cystic/pseudocystic lesions and others/miscellaneous lesions. Mucocele was the most common lesion, followed by odontoma and dentigerous cyst, which comprised 41% of total numbers of pediatric biopsied lesions. 3.A total of 6,726 diagnoses (4461 patients, 4953 lesions) were collected from OMF lesions in the geriatric patients. Most of these lesions were distributed in the inflammatory/infective group, followed by tumor/tumor-like reactive lesions. Squamous cell carcinoma was the most common lesion, and, additionally, there was a high frequency of oral potentially malignant disorders. CONCLUSION The present study showed trends consistent to previous reports from other countries; however, some detailed information differed, perhaps due to the different criteria and different geographic distribution. It was worthy of note that squamous cell carcinoma and oral potentially malignant disorders comprised high percentages of general and geriatric OMF lesions.
