Ectopic geographic tongue--a case report.

UNLABELLED: This report describes a case of 'ectopic' geographic tongue where lesions, clinically and histologically similar to those normally confined to the tongue, presented on the floor of the mouth and cheek mucosa. The patient, a type II diabetic, had a history of thrombocytopaenia and, more recently, autoimmune haemolytic anaemia.

CLINICAL RELEVANCE: Geographic tongue is a common oral medicine condition and the purpose of this paper is to highlight the fact that it can present ectopically on the oral mucosa.
