Giant cell fibroma: A clinicopathological study

Oral health of an indigenous population in northeastern Brazil: a cross-sectional Study of the Fulni-ô ethnic group

BACKGROUND

There is a lack of studies evaluating the oral health of traditional indigenous communities in Brazil.

OBJECTIVES

Thus, the objective of this study was to describe the oral health characteristics of the indigenous Fulni-ô ethnic group in Northeast Brazil.

DESIGN AND SETTING

A cross-sectional observational investigation was conducted within the Project on Atherosclerosis among Indigenous Populations.

METHODS

This study included participants of both sexes from the Fulni-ô ethnic group. The participants included in this investigation underwent a comprehensive oral health evaluation by a registered and experienced dentist to assess oral health and identify potentially malignant oral lesions. Participants with suspicious lesions were referred for biopsy. Shapiro-Wilk, Mann-Whitney, and Student's t-tests were used, and measures of central tendency and dispersion were described. Statistical significance was 5%.

RESULTS

A total of 104 individuals were included in this study. The prevalence of the use of tobacco derivatives was 94.0%, with similarities between sexes. The prevalence of oral changes in this study population was 84.4%. Fifty-one individuals who underwent oral reassessment were referred for oral lesion biopsy.

CONCLUSIONS

This study demonstrated a high prevalence of oral alterations in the Fulni-ô population. Histopathological analyses indicated the presence of mild oral epithelial dysplasia in five cases.

Benign connective and soft-tissue neoplasms of the oral and maxillofacial region: Cross-sectional study of 1066 histopathological specimens

BACKGROUND

Benign connective and soft-tissue neoplasms (CSTNs) are unusual in the head and neck region. The aim of the present study was to evaluate the demographic and clinicopathological features of these neoplasms.

METHODS

A cross-sectional study was conducted of cases diagnosed as benign CSTNs, with data collected from biopsy records. The chi-square test was used. A p-value <0.05 was considered indicative of statistical significance.

RESULTS

Among the 38 119 specimens, 1066 (2.79%) were benign CSTNs: 369 fibroblastic/myofibroblastic, 250 adipocytic, 179 vascular, 130 neural, 94 osseous/cartilaginous, 19 muscular, and two fibrohistiocytic. Most patients were female (62.8%) and white-skinned (45.8%). Mean age was 42 years. The tongue (25.2%) was the most affected site for extraosseous neoplasms.

CONCLUSION

This study had the largest sample of benign oral and maxillofacial CSTNs. Although these tumors have similar clinical features, the characterization and differentiation detailed here may help clinicians with regards to the correct diagnosis.

Relative frequency of oral focal reactive overgrowths: An institutional retrospective study

Context:

Focal fibrous hyperplasia, peripheral ossifying fibroma, pyogenic granuloma, peripheral giant cell granuloma, giant cell fibroma and focal reactive overgrowth (FROGs) are one of the foremost numerous benign soft-tissue growths in the oral cavity. Chronic irritation or trauma is with identified as the causative aspect. It may develop up to few centimeters in diameter, pedunculated or sessile and may arise on the gingiva or buccal mucosa. Treatment involves surgical excision, and recurrences are infrequent.

Aims:

The aim of this study was to assess the prevalence of FROGs of oral mucosa in an institutional setup.

Subjects and Methods:

All the histopathologically diagnosed cases of FROGs within a period of 10 years (January 2008–December 2017) were retrieved from the archives of the Department of Oral Pathology. The information such as age, sex, site, anatomical side and its prevalence were recorded on customized case history performa.

Statistical Analysis Used:

The significance of difference was assessed using the Chi-square test and Fisher's exact test.

Results:

A total of 2849 cases were identified, of which 449 (15%) were FROGs. The most prevalent lesion amid them were focal fibrous hyperplasia (277, 62%), followed by pyogenic granuloma (92, 20%), whereas the least common was giant cell fibroma with 2 (0.5%) cases. All the FROGs were distributed among 21–40 years of age showing female predominance. The commonly affected site was the right buccal mucosa.

Conclusions:

Nevertheless, information of the frequency and distribution of these lesions is favorable when establishing a diagnosis and treatment plan in clinical practice.

Giant-cell fibroma: Understanding the nature of the melanin-laden cells

Giant-cell fibroma is a localized, benign fibrous mucosal mass, which clinically mimics any other fibroepithelial growth, and its distinction from other lesions is on the basis of its peculiar histopathology. A case of giant-cell fibroma with stroma strewn with brown pigment-laden cells is presented herewith. Immunohistochemical staining aided with histochemical reaction to understand the origin of these cells was carried out. Various mechanisms that explain the presence of melanin granules in reactive lesions of giant-cell fibroma is discussed in the present report.

Proposed Clinico-Pathological Classification for Oral Exophytic Lesions

Oral exophytic lesions often have proven to be diagnostically challenging due to the varied clinical presentation. The exophytic growth of the oral lesions is due to the type of pathology and histological changes. Careful clinical interpretation with a better histological understanding of exophytic lesions may ease the diagnosis from the differential diagnosis panel. The purpose of proposing classification system is to categorize the exophytic lesions of interest under specific clinical and/or histological explanation; and this will eventually lead to better understanding of the pathological condition that is described. To the best of our knowledge, there is no such classification system available for oral exophytic lesions and hence proposal of classification system is attempted in this study. Further, proposing a new classification system is not just to influence the academic contribution, but also to assist at greatest extent for diagnosis during clinical practice.

Giant Cell Fibroma of the Buccal Mucosa with Laser Excision: Report of Unusual Case

Giant Cell Fibroma (GCF) was described as a new entity of fibrous hyperplastic soft tissue. It seems that stimulus from an unexplained origin can have a role in its etiology. Histopathologically GCF is consisted of multinucleated fibroblasts that have oval shape nuclei within the eosinophilic cytoplasm. Surgical excision is the treatment of choice and recurrence is very rare. Here we report a case of relatively large GCF in a 54-year-old man. Gingiva is the common location of GCF. As in our case, it may be mistaken as irritation fibroma especially if it is on the buccal mucosa, the most common location for fibroma. Correct diagnosis is based on biopsy and clinical examination to see surface texture roughness. To minimize bleeding because of its large size an excisional biopsy with Diod laser was performed under local anesthesia for this patient.

Giant cell fibroma in children: report of two cases and literature review

Background

Giant cell fibroma is a type of fibrous tumour of the oral mucosa which rarely affects children under the age of 10. The purpose of this paper was to contribute two clinically and histologically documented cases of giant cell fibroma in the free gingiva of a 7 and 6 year old boys.

Methods

Both nodules were presented in the mandibular anterior region. In the differential diagnosis several fibrous hyperplastic lesions were considered such as traumatic fibroma, papilloma, peripheral ossifying fibroma, peripheral odontogenic fibroma, giant cell fibroma and odontogenic hamartoma.

Results

The lesions were removed and the histological examination revealed fibrocollagenous connective tissue with the presence of stellate giant cells which confirmed the diagnosis of giant cell fibroma.

Conclusions

Dentists should be aware of the existence of giant cell fibroma in children, which must be included in the differential diagnosis of nodular lesions of the gingiva and adequately diagnosed and treated by removal and histopathological examination.

Giant cell fibroma: a case report with immunohistochemical markers

Giant cell fibroma may mimic fibroma of the gingiva, but have distinctive histopathological difference. Immunohistochemical markers are required to diagnose GCF. It may occur at any age but most often in the third decade of life. It may be often asymptomatic but may not be esthetic if present in the anterior region of the jaw. Surgical excision should be performed, and the prognosis is good. However long term follow-up is required to check for any recurrence. The most common gingival enlargements like fibroma and granuloma may be mistaken for GCF. We present a case report with histopathological markers used to diagnose GCF.
