FIRST PARAGRAPH: A traumatic ulcer is a chronic traumatic ulceration of the oral mucosa that shows unique histopathologic features. Also known as traumatic granuloma, eosinophilic granuloma, and Riga-Fede disease, this lesion is usually caused by some sort of mechanical injury. The most common causes include accidental trauma from biting, malposed teeth, and even sharp foodstuffs. However, self inflicted wounds caused by nocturnal clenching or tongue and lip biting, electrical and thermal injuries, hot foods or beverages, and even factitial injuries yield a similar finding. Ulceration of the ventral tongue as a result of tongue thrusting in infants with natal or neonatal teeth is referred to as Riga-Fede disease.
