Irritation Fibroma Of The Oral Mucosa – A Clinicopathologial Study Of 101 Cases

Abstract

A form of such a controlled cell proliferation is hyperplasia which is one method by which cells adapt to stress. Hyperplasia constitutes an increase in the number of cells in an organ or tissue. Hyperplastic lesions are common in the oral cavity, because of the frequency with which the oral tissues are traumatized. Because these conditions are a reaction to some irritant, they are often called 'reactive lesions'. Irritation fibroma also known as traumatic fibroma, focal fibrous hyperplasia and hyperplastic scar, is a reactive lesion caused usually by chronic trauma to oral mucous membranes. It is a very common reactive hyperplasia that is typically found in traumatized areas such as the buccal mucosa, lateral border of tongue and lower lip. It is a painless broad based swelling that is lighter in colour than the surrounding tissue because of its reactive lack of vascular channels. Although irritation fibroma is one of the most common lesions among intraoral exophytic lesions of the soft tissues,¹² there have been few studies of this lesion.
