[Unusual traumatic alterations of the tongue (author's transl)].

A baby with congenital sensoric neuropathy showed, due to missing sensitivity to pain, repeated injury of the tongue resulting from bites after the front teeth had erupted. The defect formed at the tip of the tongue and showed excessive granulation resembling at first sight a tumorous process. Such alterations of the tongue usually are the first symptom of this rare disease and therefore are most important for diagnosis. With another infant presenting with Joubert's syndrome, i.e. cerebellar malformation, macroglossy, increased motility of the tongue and severe dyspnoic attacks combined with seizures, also tumorous granulomatous alterations of the tongue were found, due to chronic injury of the tongue by bites.
