Localized gingival enlargements. A clinicopathological study of 1187 cases

Abstract

Background: To describe the incidence, demographic and clinical features of 1187 localized gingival enlargements. Material and Methods: 1187 cases of localized gingival enlargements diagnosed during a 20-year period were retrospectively collected. The patients’ gender and age, as well as the main clinical features of the tumors were retrieved from the biopsy report forms. Results: The 1187 localized gingival enlargements represented 6.23% of 19.044 biopsies performed during the study period. 756 females and 427 males were affected with a mean age of 41.92±19.68 years. The lesions appeared as smooth (52.4%), granular (17.9%) or rough (13.16%) tumors, elastic (50.73%) or soft (29.56%) in consistency and red (60.8%), normal (28.58%) or white (8.17%) in color. The majority of the lesions (85.17%) were reactive in origin with pyogenic granuloma being the most common. In 1.1% of the cases a diagnosis of malignant lesion was rendered. Conclusions: All localized gingival enlargements should be submitted for microscopic examination because in approximately 1% of cases they are malignant.
