Ulcerative eosinophilic granuloma: a report of five new cases.

Five new cases of ulcerative eosinophilic granuloma were diagnosed at the Massachusetts General Hospital between 1982 and 1993. In all cases the site was the tongue. They were unifocal, did not recur, and had a benign course. This report illustrates their benign nature despite the occasional aggressive presentation, and outlines possible aetiology.
