Oral lesions can be observed and usually consist of a solitary, painful ulceration that occurs on the palate, tongue, or buccal mucosa. The gumma is a zone of granulomatous inflammation which may present as an indurated, nodular, ulcerated lesion. Intraoral involvement typically affects the palate or the tongue. This condition most frequently is associated with the minor salivary glands of the palate. It is usually observed in adult males and presents as an asymptomatic, necrotic, ulcerated area involving the palatal mucosa.
Clinical history is usually helpful in determining the source of the injury.
