Delayed hypersensitivity or geographic tongue: A diagnostic dilemma

We report the case of a patient who presented to us with burning and itching sensations on the tongue three days after restoration of his lower permanent molars with silver amalgam. Within a day, the initially well circumscribed lesions of the tongue became diffuse. Atrophy of the lingual papillae gave an appearance of a geographic tongue. Following replacement of the amalgam restoration, symptoms rapidly subsided and there was a significant improvement of the lesion.
