[Experimental study on the "traumatogenic" eosinophilic granuloma of the tongue].

According to Bhaskar and Lilly, experimental results with rat tongues indicated that trauma is the cause of the rare eosinophilic granuloma of the human tongue. On the basis of similar experimental investigations, we consider this conclusion to be incorrect. In our opinion, the etiology of eosinophilic granuloma of the tongue as that of other eosinophilic granulomas in man is still unknown.
