A 34-year-old female patient presented with the complaint of a mass lesion of about 1 cm in diameter, with a gradually enlarging, painless, nearly round shape, close to the oral mucosa, on the right cheek mucosa. An excisional biopsy was performed from the patient's intraoral mucosa, and the mass was surgically removed (after local anesthetic infiltration, a knot was tied at the bottom of the lesion with self-dissolving suture material and the lesion was surgically removed by cutting with scissors with a firm border). In the photo above and below, there is a view of the lesion before and after the excision of the lesion, after resection. Histopathological examination reported as traumatic fibroma. A consultation examination was requested from the dentist in order to evaluate the everted molar teeth that irritate the patient's buccal mucosa.

Localized fibrotic tissue growths often occur in the oral mucosa. Different mechanisms are effective in their formation. The most common mechanisms are reactive hyperplasia and neoplasia. It is often in the form of hyperplasia, and true fibroma and true neoplasms are rarely seen. Localized fibrous lesions of the oral mucosa that are not neo-plastic in character are different in the oral pathology and oral surgery literature such as irritation fibroma, irritable fibroma, traumatic fibroma, fibrous hyperplasia, focal fibrous hyperplasia, localized fibrous hyperplasia, fibrous polyps, fibrous nodules or fibroepithelial polyps.

Irritation fibroma, also called traumatic fibroma, focal fibrous hyperplasia, hyperplastic scar; It is a benign, localized, peripheral, tumor-like lesion originating from connective tissue. It usually develops secondary to chronic irritation or trauma. Traumatic fibroma or irritation fibroma can be defined as the final state of an inflammatory hyperplastic lesion after healing. It can occur after a single acute trauma or may develop after repeated milder traumas, chronic inflammation or infection. It is typically seen on the cheek mucosa, lateral of the tongue and lower lip, which are more exposed to trauma. However, it can be seen all over the mouth. It is one of the most common lesions of the oral mucosa and its prevalence is 1.2% in adults. In addition, it can be seen in both sexes equally and at all ages. However, it is mostly seen in adults.

Clinically; It is round or ovoid-shaped, its surface is generally smooth, asymptomatic, and is seen in the same color as the surrounding healthy mucosa. The surface of the lesion can sometimes be hyperkeratotic or ulcerated due to repetitive trauma. They are generally seen in a diameter smaller than 1 cm. Lesions larger than 1 cm are rare. Histopathologically; It is a lesion with a large number of mature fibroblasts scattered in a dense collagen matrix consisting of a mixture of type 1 and type 3 collagen. It shows irregular hyperplastic epithelium and small superficial erosions due to excessive collagen production. Malignant transformation of irritation fibroma is not seen. In addition, squamous cell carcinoma cases with clinical appearance as irritation fibroma have been reported in the literature.

Irritation fibroma histopathologically is a lesion with irregular surface hyperplastic epithelium and local micro erosive regions due to excessive collagen production. Therefore, histopathologically, there is no malignant predisposing finding in these lesions. However, the lesion
The chronic irritant factor should be eliminated in order to treat or prevent recurrence after treatment. In this case, the chronic irritant factor was the patient's habit of sucking a pencil. In order to prevent the recurrence of the lesion after surgical intervention, the patient was advised to prevent this habit.
