[Eosinophilic ulcer of the tongue. Pathogenic role of eosinophils].

A male patient with an ulcerative lesion on the edge of his tongue is present. The histopathologic findings were typical for "Eosinophilic Ulcer of the Tongue". This was contiguous with a carious molar, the remotion of which was followed by total remission of the ulcer. Its possible aetiology and pathogenesis are discussed. Based on the injurious effects of eosinophils mentioned in anothers affections the authors postulate that eosinophils may have an important rol in production or maintainance of this ulcer.
