EOSINOPHILIC ULCER OF THE ORAL-MUCOSA - REPORT OF A RECURRENT CASE ONTHE TONGUE

Eosinophilic ulcer of the oral mucosa (EUOM) is an uncommon lesion tha t usually affects the tongue. The lesion is benign and self-limiting, develops rapidly and usually disappears after several weeks without tr eatment. Microscopically, it contains a diffuse polymorphous cell infi ltrate composed mainly of eosinophils. The cause of EUOM is unknown, b ut 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 d orsal surface 3 years later. The occurrence of multiple lesions, wheth er at the same time or subsequently as reported here, makes a purely t raumatic origin rather unlikely and suggests that there may be a predi sposition of some patients to develop EUOM.
