Eosinophilic ulcer of the oral mucosa: report of a recurrent case on the tongue.
Eosinophilic ulcer of the oral mucosa (EUOM) is an uncommon lesion that usually affects the tongue. The lesion is benign and self-limiting, develops rapidly and usually disappears after several weeks without treatment. Microscopically, it contains a diffuse polymorphous cell infiltrate composed mainly of eosinophils. The cause of EUOM is unknown, but the condition has been attributed to trauma. We now describe a case of EUOM on the lateral surface of the tongue with recurrence on its dorsal surface 3 years later. The occurrence of multiple lesions, whether at the same time or subsequently as reported here, makes a purely traumatic origin rather unlikely and suggests that there may be a predisposition of some patients to develop EUOM. Eosinophilic ulcer of the oral mucosa (EUOM) is an uncommon lesion that is very rarely reported in the dermatological literature. It usually affects the tongue and presents clinically as an ulcer with elevated and indurated borders. Recognition is important because it often mimicks tongue cancer; however, the lesion is benign and self-limiting, develops rapidly and usually disappears after several weeks without treatment. Usually the ulcer occurs in a single episode, but the possibility of recurrence at other sites has been poorly emphasized.
