A case of irritation fibroma

Conventional Scalpel and Diode Laser Approach for the Management of Traumatic Fibroma

An oral fibroma is a benign scar-like reaction frequently resulting from chronic mouth irritation. It is also called an oral polyp, fibrous nodule, localised intraoral fibrous hyperplasia, and traumatic fibroma. Chronic irritation from things like biting one's lips or cheek, orthodontic treatments, rubbing against a hard tooth, or wearing dentures or other dental prostheses is frequently the cause. It is often the same colour as the surrounding mouth lining, but occasionally, it can be paler or appear darker if it has bled. Trauma can cause the surface to become rough and scaly or ulcerated. It is primarily dome-shaped and similar to a pedunculated polyp. A traumatic fibroma most frequently occurs on the inside of the cheek. The inside of the lower lip, the gingiva, and the sides of the tongue are other frequent locations. The given case series reported traumatic fibroma associated with anterior teeth and buccal mucosa treated with a conventional scalpel and diode laser techniques, respectively. Diagnosing and treating the aetiology and educating the patient about the same is essential in fibroma cases. The clinical features of both claims and mere aetiology confirmed the diagnosis. The sole option available when therapy is needed is a surgical fibroma excision. Surgical excision is the most popular method for treating oral or traumatic fibromas. Two ways are available for the surgical removal of an oral fibroma: with a scalpel or using a diode laser. Both case presentations demonstrate that surgical excision with a scalpel and diode laser was discovered to be a simple, efficient, and affordable method for treating traumatic fibroma in this report, which presents two traumatic fibromas with different locations with varying aetiology. Traumatic fibromas reported here were in the aesthetic zones, which need to be treated as they can cause traumatic occlusion and difficulty chewing and speech. The patients reviewed for the next three months revealed complete satisfactory healing and no recurrence in both cases.

Oral fibroepithelial polyps ("chewing granulomas") in 21 dogs: Histomorphology, immunohistochemical characterization, and clinical outcome

Oral fibroepithelial polyps (FEPs) are common, benign, nonneoplastic lesions in humans that often develop slowly in sites of local irritation or trauma. This study analyzed 23 oral fibroepithelial polypoid lesions retrieved from 21 dogs (2014-2021). All lesions were pedunculated with usually an irregular/cauliflower-like or rarely smooth surface. FEPs most commonly arose under or lateral to the tongue; other sites included the labial and gingival mucosa, soft palate, and hard palate. All the lesions were characterized by a thick fibrovascular stalk consisting of bundles of fibrocytes and fibroblasts embedded in a collagenous matrix rich in blood vessels. The surface squamous epithelium, when evaluable, was hyperplastic (22/22; 100%) with frequent parakeratotic hyperkeratosis (12/22; 54.5%). Ulceration of variable extent was observed in 13/23 cases (56.5%). Inflammation was associated with 18/23 cases (78.3%), and was mostly lymphoplasmacytic. The connective tissue was consistently immunoreactive for vimentin and generally negative for smooth muscle actin and desmin. All FEPs in cases with available clinical outcome data did not recur after surgical excision. The presence of chronic inflammation and ulceration suggests a causative role of chronic irritation in the pathogenesis of canine oral FEPs. FEPs should be included among the differential diagnoses of proliferative lesions of the oral cavity in dogs.

Histopathological analysis of the association between mucosal epithelial changes and the lamina propria vascular network in irritation fibroma

OBJECTIVES

Irritation fibroma in the oral cavity causes atrophy or squamous epithelium thickening with respect to external injury-associated factors. However, ulcers do not occur in most cases. This study aimed to elucidate the mechanism by which ulcers do not form, focusing on the vascular network in the mucosal epithelium of irritation fibroma.

METHODS

Immunostaining was performed using an enzyme antibody method with primary antibodies against CD31 and Ki-67 in 17 cases of irritation fibroma in the buccal mucosa. One section was taken at three points from the margin and three points from just above the lesion for measurement. The number of blood vessels in the superficial and deep lamina propria at the measurement site were determined, and the area per blood vessel was measured.

RESULTS

The number and area of blood vessels in the superficial lamina propria just below the lesion epithelium were smaller than those in the margin. No difference was observed in the number and area of blood vessels in the deep lamina propria between the margins and lesions.

CONCLUSIONS

Our results suggest that the vascular network in the deep lamina propria is maintained and compensates for the nutrient supply to the covering epithelium.

Application of mucous membrane dermoscopy (mucoscopy) in diagnostics of benign oral lesions - literature review and preliminary observations from International Dermoscopy Society study

Dermoscopy of mucosal surface termed "mucoscopy" is an upcoming offshoot of dermatological imaging. However, the literature on mucoscopy is limited to individual cases and small case series. An organized review or systematic analysis of mucoscopy is lacking. The aim of this review was to summarize the published literature on mucoscopic features of benign conditions affecting the oral mucosa and semi-mucosa. Additionally, the results of mucoscopic features of diseases, which have not been described before have been presented.

Chronic Oral Lesions

Chronic oral mucosal lesions can be associated with several mucocutaneous diseases. This article reviews the autoimmune and immune-mediated, reactive, genetic, and infectious diseases that may present with chronic oral and/or cutaneous manifestations and provides a rational approach to diagnosis and management.
