We hereby report an unusual case which presented as a routinely encountered reactive lesion on the palate, whilst the radiological examination revealed a radiolucent cystic lesion underneath. After the investigations from radiography to histopathology, it was finally diagnosed as a peripheral ossifying fibroma coexisting with a nasopalatine duct cyst. [ABSTRACT FROM AUTHOR]

Objectives: Aim of the present study was clinical and histopathological evaluation of a series of epulides to provide clinicians data to frequency distribution and biological behaviour of different underlying entities. Materials and methods: Ninety-two cases of epulides removed by CO-laser at the Department of Oral Surgery and Radiology, Medical University of Graz from 2000 to 2014 were studied retrospectively for clinical data and histopathological diagnosis. Results: In the presented study, histopathological examination revealed peripheral ossifying fibroma (32.6 %), fibroma/fibrosis (29.3 %), giant cell lesion (13.1 %) and granuloma pyogenicum (8.7 %) as the most frequent underlying entities. For the first time, hyperplastic squamous epithelium (7.6 %), granulation tissue (5.4 %) and peripheral odontogenic fibromas (3.3 %) were detected to clinically appear as epulides. Irrespective of the histological diagnosis, the mean age in our patients was 43.8 years. The majority of the lesions were found in the frontal region of both jaws. In all cases, the patients showed poor oral hygiene, local gingivitis and some of them an occlusal trauma. Conclusions: To identify different entities with different biological behaviour, to exclude malignant tumours and to identify new entities among epulides, histopathological examination is required. Poor oral hygiene and occlusal trauma seem to play an important role in the pathogenesis and could be risk factors for recurrences. Clinical relevance: Frequency distribution of different entities in epulides is provided to clinicians, and new histopathological entities were detected to clinically appear as epulides.

Background: Biopsy is an important diagnostic tool used in the diagnosis of lesions ranging from simple non-neoplastic, tumor-like lesions to malignancies, and is often the only way to diagnose oral lesions and diseases. The gingiva is the most common site for some kind of irritation or low-grade injury, resulting in localized overgrowths that are considered to be reactive and non-neoplastic lesions. This aim of this study is to analyze the frequency and distribution of gingival lesions in the Gujarati population. Materials and Methods: In this retrospective study, gingival biopsies submitted for a period of five years were included. Microscopic slides of all the cases were reviewed by two observers for confirmation of the diagnosis. Results: Among the 106 cases of gingival biopsies, the most frequent category of lesions encountered was the non-neoplastic category, which accounted for 73.58% of the cases. Both benign and malignant neoplasms constituted 26.42% of the cases. Among the non-neoplastic lesions, Pyogenic granuloma was the most frequent lesion (38.46%), followed by fibrous hyperplasia (20.51%), inflammatory hyperplasia (19.23%), and Epulis (8.97%). Neoplasms accounted for 26.42% of the gingival biopsies (92.85% benign and 7.15% malignant). Among the benign neoplastic lesions, Fibroma (30.76%) and Fibrolipoma (26.92%) were the most frequent, followed by peripheral ossifying fibroma (23.08%) and peripheral giant cell granuloma (11%). Conclusion: It is difficult to compare studies carried out in various countries due to differences in people's attitudes toward oral health and the accessibility of various population groups to biopsy services. Nevertheless, this study has provided some information about the frequency and distribution of biopsied gingival lesions in the Gujarati population over a period of five years. [ABSTRACT FROM AUTHOR]
