ABSTRACT

INTRODUCTION: In a clinicopathological retrospective epidemiological study we investigated benign tumors and tumor-like lesions located in the orofacial region, diagnosed at the Universiy of Szeged, Department of Oral Medicine. METHOD: During a 54-year period (1960-2014), 14 661 biopsies were taken. The included subjects were 7491 patients diagnosed with benign tumors and tumor-like lesions. RESULTS: The average age of patients was 55.3 years, 2823 (37.7%) patients were male and 4668 (62.3%) female. The male  female ratio was 1  1.65. Most of the patients included in the study were aged 51-60 (1280, 17.1%). The number of children was 1014 (13.6%) and the number of adults was 6477 (86.3%). The number of non-neoplasms was 6420 (85.7%), being significantly higher than the number of neoplasms (1071, 14.3%). Most of the lesions were of mesenchymal origin (5574, 77.4%); the number of lesions of non-mesenchymal origin was 982 (13.1%). The most prevalent type of lesions was traumatic fibroma (fibrosis) 1806 (32.4%). The most common lesion type in the group of lesions of infectious/inflammational origin was pyogenic granuloma, the number of which was 465 (8.3%). The most common cystic lesion was mucocele (805, 10.7%). Hemangioma was the most frequent lesion type among developmental anomalies with the number of 815 (14.6%). The most common location of the lesions was the lip in 2081 cases (27.8%), followed by the gingiva in 2024 cases (27.0%), bucca in 1069 cases (14.3%), tongue in 981 cases (13.1%), and the facial skin in 695 cases (9.3%). After taking biopsy, the majority of benign lesions were treated with cryo-, laser-, or combined (cryo and laser) surgery. CONCLUSION: The present computer-aided study showed that irritational fibroma was the most common orofacial benign tumor, and the lip was the most frequent location. The diagnostic classification and the methodology are considerably different in the majority of the studies, which may hinder the exact comparison with other surveys from different regions of the world.
