Fibroma

Fibro-epithelial polyp or fibrous hyperplasia is the most common benign soft tissue tumors seen in the oral cavity (10). Fibroma occurs as a result of a chronic repair process that includes granulation tissue and scar formation resulting in a submucosal fibrous mass (11). Axell reported the prevalence of 3.25% for fibroma in the adult Swedish population (12). They rarely occur before fourth decade of life and have no gender predilection (12). In the present case both the patients were in early second decade of life, thereby a variation was observed, conflicting the general affected age group as per literature overview. The clinical features of fibro-epithelial polyp is not exclusive and the lesion must be differentiated from peripheral ossifying fibroma, peripheral giant cell granuloma. Peripheral ossifying
The differential diagnosis of fibro-epithelial polyp is done based on the location of the soft tissue swelling. If it is located on the tongue, the possibility of neurofibroma, neurilemmoma or granular cell tumor must be considered. Swelling on the lower lip or buccal mucosa, may suggest the possibility of a mucocele, lipoma or salivary gland tumor. Another important differentiating feature is : histopathologically, traumatic fibroma exhibit two different patterns of collagen arrangement depending on the amount of irritation and the site of the lesion;(a) Radiating pattern has been found to be associated with sites, which are immobile in nature (e.g. palate) and have a greater degree of trauma, (b) circular pattern is found to be associated with sites that are flexible in nature and have lesser degree of trauma (e.g. cheeks) whereas true fibroma does not show any of the patterns (14). Fibro epithelial polyp does not hold a risk for malignancy.7 Recurrences rates are low (15) and are mostly caused by repetitive trauma at site of the
